Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650280, here are decompositions:

  • 61 + 8650219 = 8650280
  • 127 + 8650153 = 8650280
  • 139 + 8650141 = 8650280
  • 151 + 8650129 = 8650280
  • 157 + 8650123 = 8650280
  • 193 + 8650087 = 8650280
  • 229 + 8650051 = 8650280
  • 241 + 8650039 = 8650280

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 8,650,280 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 8650280 first appears in π at position 930,960 of the decimal expansion (the 930,960ordinal-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.
