Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138056, here are decompositions:

  • 3 + 138053 = 138056
  • 73 + 137983 = 138056
  • 109 + 137947 = 138056
  • 229 + 137827 = 138056
  • 313 + 137743 = 138056
  • 349 + 137707 = 138056
  • 397 + 137659 = 138056
  • 433 + 137623 = 138056

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 138,056 and was likely granted around 1872.

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