Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135738, here are decompositions:

  • 7 + 135731 = 135738
  • 11 + 135727 = 135738
  • 17 + 135721 = 135738
  • 19 + 135719 = 135738
  • 37 + 135701 = 135738
  • 41 + 135697 = 135738
  • 67 + 135671 = 135738
  • 89 + 135649 = 135738

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 135,738 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 135738 first appears in π at position 523,997 of the decimal expansion (the 523,997ordinal-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.
