Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651486, here are decompositions:

  • 43 + 8651443 = 8651486
  • 97 + 8651389 = 8651486
  • 127 + 8651359 = 8651486
  • 157 + 8651329 = 8651486
  • 163 + 8651323 = 8651486
  • 307 + 8651179 = 8651486
  • 367 + 8651119 = 8651486
  • 439 + 8651047 = 8651486

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 8,651,486 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 8651486 first appears in π at position 863,821 of the decimal expansion (the 863,821ordinal-suffix:st 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.
