Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668874, here are decompositions:

  • 37 + 8668837 = 8668874
  • 43 + 8668831 = 8668874
  • 61 + 8668813 = 8668874
  • 73 + 8668801 = 8668874
  • 163 + 8668711 = 8668874
  • 373 + 8668501 = 8668874
  • 601 + 8668273 = 8668874
  • 607 + 8668267 = 8668874

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 8,668,874 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 8668874 first appears in π at position 793,545 of the decimal expansion (the 793,545ordinal-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.
