Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650442, here are decompositions:

  • 13 + 8650429 = 8650442
  • 19 + 8650423 = 8650442
  • 223 + 8650219 = 8650442
  • 313 + 8650129 = 8650442
  • 439 + 8650003 = 8650442
  • 571 + 8649871 = 8650442
  • 739 + 8649703 = 8650442
  • 751 + 8649691 = 8650442

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 8,650,442 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 8650442 first appears in π at position 373,040 of the decimal expansion (the 373,040ordinal-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.
