Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139850, here are decompositions:

  • 13 + 139837 = 139850
  • 19 + 139831 = 139850
  • 37 + 139813 = 139850
  • 97 + 139753 = 139850
  • 103 + 139747 = 139850
  • 223 + 139627 = 139850
  • 241 + 139609 = 139850
  • 313 + 139537 = 139850

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 139,850 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 139850 first appears in π at position 951,089 of the decimal expansion (the 951,089ordinal-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.
