Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666738, here are decompositions:

  • 307 + 8666431 = 8666738
  • 571 + 8666167 = 8666738
  • 601 + 8666137 = 8666738
  • 739 + 8665999 = 8666738
  • 1021 + 8665717 = 8666738
  • 1087 + 8665651 = 8666738
  • 1171 + 8665567 = 8666738
  • 1297 + 8665441 = 8666738

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,666,738 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8666738 first appears in π at position 574,089 of the decimal expansion (the 574,089ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
