Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139010, here are decompositions:

  • 43 + 138967 = 139010
  • 73 + 138937 = 139010
  • 127 + 138883 = 139010
  • 181 + 138829 = 139010
  • 211 + 138799 = 139010
  • 271 + 138739 = 139010
  • 283 + 138727 = 139010
  • 331 + 138679 = 139010

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 139,010 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 139010 first appears in π at position 327,518 of the decimal expansion (the 327,518ordinal-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.
