Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139462, here are decompositions:

  • 3 + 139459 = 139462
  • 5 + 139457 = 139462
  • 23 + 139439 = 139462
  • 53 + 139409 = 139462
  • 101 + 139361 = 139462
  • 149 + 139313 = 139462
  • 263 + 139199 = 139462
  • 293 + 139169 = 139462

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 139,462 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 139462 first appears in π at position 233,921 of the decimal expansion (the 233,921ordinal-suffix:st 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.
