Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650128, here are decompositions:

  • 5 + 8650123 = 8650128
  • 7 + 8650121 = 8650128
  • 41 + 8650087 = 8650128
  • 89 + 8650039 = 8650128
  • 101 + 8650027 = 8650128
  • 191 + 8649937 = 8650128
  • 199 + 8649929 = 8650128
  • 241 + 8649887 = 8650128

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 8,650,128 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 8650128 first appears in π at position 741,487 of the decimal expansion (the 741,487ordinal-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.
