Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688878, here are decompositions:

  • 61 + 8688817 = 8688878
  • 139 + 8688739 = 8688878
  • 181 + 8688697 = 8688878
  • 271 + 8688607 = 8688878
  • 277 + 8688601 = 8688878
  • 307 + 8688571 = 8688878
  • 409 + 8688469 = 8688878
  • 607 + 8688271 = 8688878

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 8,688,878 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 8688878 first appears in π at position 248,398 of the decimal expansion (the 248,398ordinal-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.
