Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139232, here are decompositions:

  • 31 + 139201 = 139232
  • 109 + 139123 = 139232
  • 199 + 139033 = 139232
  • 211 + 139021 = 139232
  • 349 + 138883 = 139232
  • 433 + 138799 = 139232
  • 439 + 138793 = 139232
  • 571 + 138661 = 139232

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 139,232 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 139232 first appears in π at position 207,352 of the decimal expansion (the 207,352ordinal-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.
