Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138934, here are decompositions:

  • 11 + 138923 = 138934
  • 17 + 138917 = 138934
  • 41 + 138893 = 138934
  • 71 + 138863 = 138934
  • 113 + 138821 = 138934
  • 137 + 138797 = 138934
  • 251 + 138683 = 138934
  • 293 + 138641 = 138934

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 138,934 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 138934 first appears in π at position 19,227 of the decimal expansion (the 19,227ordinal-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.
