Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139162, here are decompositions:

  • 29 + 139133 = 139162
  • 41 + 139121 = 139162
  • 53 + 139109 = 139162
  • 71 + 139091 = 139162
  • 83 + 139079 = 139162
  • 239 + 138923 = 139162
  • 263 + 138899 = 139162
  • 269 + 138893 = 139162

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 139,162 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 139162 first appears in π at position 70,535 of the decimal expansion (the 70,535ordinal-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.
