Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646838, here are decompositions:

  • 17 + 8646821 = 8646838
  • 59 + 8646779 = 8646838
  • 131 + 8646707 = 8646838
  • 257 + 8646581 = 8646838
  • 359 + 8646479 = 8646838
  • 449 + 8646389 = 8646838
  • 461 + 8646377 = 8646838
  • 509 + 8646329 = 8646838

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 8,646,838 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 8646838 first appears in π at position 257,303 of the decimal expansion (the 257,303ordinal-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.
