Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666998, here are decompositions:

  • 5 + 8666993 = 8666998
  • 59 + 8666939 = 8666998
  • 71 + 8666927 = 8666998
  • 107 + 8666891 = 8666998
  • 149 + 8666849 = 8666998
  • 191 + 8666807 = 8666998
  • 251 + 8666747 = 8666998
  • 317 + 8666681 = 8666998

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 8,666,998 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 8666998 first appears in π at position 506,519 of the decimal expansion (the 506,519ordinal-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.
