Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138032, here are decompositions:

  • 163 + 137869 = 138032
  • 229 + 137803 = 138032
  • 241 + 137791 = 138032
  • 373 + 137659 = 138032
  • 379 + 137653 = 138032
  • 409 + 137623 = 138032
  • 439 + 137593 = 138032
  • 541 + 137491 = 138032

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 138,032 and was likely granted around 1872.

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