Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613812, here are decompositions:

  • 3 + 8613809 = 8613812
  • 61 + 8613751 = 8613812
  • 73 + 8613739 = 8613812
  • 79 + 8613733 = 8613812
  • 241 + 8613571 = 8613812
  • 283 + 8613529 = 8613812
  • 331 + 8613481 = 8613812
  • 349 + 8613463 = 8613812

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 8,613,812 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8613812 first appears in π at position 961,383 of the decimal expansion (the 961,383ordinal-suffix:rd 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.
