Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137500, here are decompositions:

  • 17 + 137483 = 137500
  • 23 + 137477 = 137500
  • 47 + 137453 = 137500
  • 53 + 137447 = 137500
  • 101 + 137399 = 137500
  • 107 + 137393 = 137500
  • 113 + 137387 = 137500
  • 131 + 137369 = 137500

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 137,500 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 137500 first appears in π at position 142,932 of the decimal expansion (the 142,932ordinal-suffix:nd 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.
