Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139358, here are decompositions:

  • 19 + 139339 = 139358
  • 61 + 139297 = 139358
  • 67 + 139291 = 139358
  • 157 + 139201 = 139358
  • 181 + 139177 = 139358
  • 337 + 139021 = 139358
  • 421 + 138937 = 139358
  • 619 + 138739 = 139358

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 139,358 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
