Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725212, here are decompositions:

  • 5 + 8725207 = 8725212
  • 29 + 8725183 = 8725212
  • 53 + 8725159 = 8725212
  • 59 + 8725153 = 8725212
  • 71 + 8725141 = 8725212
  • 73 + 8725139 = 8725212
  • 79 + 8725133 = 8725212
  • 101 + 8725111 = 8725212

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 8,725,212 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 8725212 first appears in π at position 563,911 of the decimal expansion (the 563,911ordinal-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.
