Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665930, here are decompositions:

  • 17 + 8665913 = 8665930
  • 41 + 8665889 = 8665930
  • 113 + 8665817 = 8665930
  • 131 + 8665799 = 8665930
  • 227 + 8665703 = 8665930
  • 263 + 8665667 = 8665930
  • 281 + 8665649 = 8665930
  • 311 + 8665619 = 8665930

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 8,665,930 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 8665930 first appears in π at position 502,389 of the decimal expansion (the 502,389ordinal-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.
