Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625180, here are decompositions:

  • 7 + 8625173 = 8625180
  • 59 + 8625121 = 8625180
  • 61 + 8625119 = 8625180
  • 89 + 8625091 = 8625180
  • 97 + 8625083 = 8625180
  • 103 + 8625077 = 8625180
  • 107 + 8625073 = 8625180
  • 127 + 8625053 = 8625180

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 8,625,180 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 8625180 first appears in π at position 57,659 of the decimal expansion (the 57,659ordinal-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.
