Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139292, here are decompositions:

  • 19 + 139273 = 139292
  • 271 + 139021 = 139292
  • 409 + 138883 = 139292
  • 463 + 138829 = 139292
  • 499 + 138793 = 139292
  • 613 + 138679 = 139292
  • 631 + 138661 = 139292
  • 733 + 138559 = 139292

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 139,292 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 139292 first appears in π at position 464,985 of the decimal expansion (the 464,985ordinal-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.
