Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681992, here are decompositions:

  • 3 + 8681989 = 8681992
  • 23 + 8681969 = 8681992
  • 353 + 8681639 = 8681992
  • 443 + 8681549 = 8681992
  • 479 + 8681513 = 8681992
  • 503 + 8681489 = 8681992
  • 509 + 8681483 = 8681992
  • 563 + 8681429 = 8681992

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 8,681,992 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 8681992 first appears in π at position 895,524 of the decimal expansion (the 895,524ordinal-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.
