Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646630, here are decompositions:

  • 23 + 8646607 = 8646630
  • 59 + 8646571 = 8646630
  • 71 + 8646559 = 8646630
  • 101 + 8646529 = 8646630
  • 127 + 8646503 = 8646630
  • 151 + 8646479 = 8646630
  • 173 + 8646457 = 8646630
  • 227 + 8646403 = 8646630

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 8,646,630 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 8646630 first appears in π at position 138,539 of the decimal expansion (the 138,539ordinal-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.
