Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139636, here are decompositions:

  • 17 + 139619 = 139636
  • 47 + 139589 = 139636
  • 89 + 139547 = 139636
  • 149 + 139487 = 139636
  • 179 + 139457 = 139636
  • 197 + 139439 = 139636
  • 227 + 139409 = 139636
  • 239 + 139397 = 139636

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 139,636 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 139636 first appears in π at position 739,543 of the decimal expansion (the 739,543ordinal-suffix:rd 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.
