Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137580, here are decompositions:

  • 7 + 137573 = 137580
  • 13 + 137567 = 137580
  • 43 + 137537 = 137580
  • 61 + 137519 = 137580
  • 73 + 137507 = 137580
  • 89 + 137491 = 137580
  • 97 + 137483 = 137580
  • 103 + 137477 = 137580

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 137,580 and was likely granted around 1872.

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