Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646730, here are decompositions:

  • 11 + 8646719 = 8646730
  • 23 + 8646707 = 8646730
  • 47 + 8646683 = 8646730
  • 149 + 8646581 = 8646730
  • 227 + 8646503 = 8646730
  • 233 + 8646497 = 8646730
  • 251 + 8646479 = 8646730
  • 353 + 8646377 = 8646730

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 8,646,730 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 8646730 first appears in π at position 806,060 of the decimal expansion (the 806,060ordinal-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.
