Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737572, here are decompositions:

  • 29 + 8737543 = 8737572
  • 43 + 8737529 = 8737572
  • 71 + 8737501 = 8737572
  • 83 + 8737489 = 8737572
  • 89 + 8737483 = 8737572
  • 113 + 8737459 = 8737572
  • 139 + 8737433 = 8737572
  • 149 + 8737423 = 8737572

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 8,737,572 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 8737572 first appears in π at position 542,740 of the decimal expansion (the 542,740ordinal-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.
