Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137224, here are decompositions:

  • 5 + 137219 = 137224
  • 23 + 137201 = 137224
  • 41 + 137183 = 137224
  • 47 + 137177 = 137224
  • 71 + 137153 = 137224
  • 107 + 137117 = 137224
  • 137 + 137087 = 137224
  • 233 + 136991 = 137224

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 137,224 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 137224 first appears in π at position 721,756 of the decimal expansion (the 721,756ordinal-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.
