Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137824, here are decompositions:

  • 47 + 137777 = 137824
  • 53 + 137771 = 137824
  • 101 + 137723 = 137824
  • 191 + 137633 = 137824
  • 227 + 137597 = 137824
  • 251 + 137573 = 137824
  • 257 + 137567 = 137824
  • 317 + 137507 = 137824

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 137,824 and was likely granted around 1872.

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