Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667868, here are decompositions:

  • 5 + 8667863 = 8667868
  • 47 + 8667821 = 8667868
  • 59 + 8667809 = 8667868
  • 71 + 8667797 = 8667868
  • 179 + 8667689 = 8667868
  • 191 + 8667677 = 8667868
  • 227 + 8667641 = 8667868
  • 257 + 8667611 = 8667868

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 8,667,868 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 8667868 first appears in π at position 881,441 of the decimal expansion (the 881,441ordinal-suffix:st 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.
