Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137744, here are decompositions:

  • 7 + 137737 = 137744
  • 31 + 137713 = 137744
  • 37 + 137707 = 137744
  • 151 + 137593 = 137744
  • 157 + 137587 = 137744
  • 307 + 137437 = 137744
  • 331 + 137413 = 137744
  • 547 + 137197 = 137744

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 137,744 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 137744 first appears in π at position 442,585 of the decimal expansion (the 442,585ordinal-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.
