Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139708, here are decompositions:

  • 5 + 139703 = 139708
  • 11 + 139697 = 139708
  • 47 + 139661 = 139708
  • 89 + 139619 = 139708
  • 137 + 139571 = 139708
  • 197 + 139511 = 139708
  • 251 + 139457 = 139708
  • 269 + 139439 = 139708

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 139,708 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 139708 first appears in π at position 615,058 of the decimal expansion (the 615,058ordinal-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.
