Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137736, here are decompositions:

13 + 137723 = 137736
23 + 137713 = 137736
29 + 137707 = 137736
37 + 137699 = 137736
83 + 137653 = 137736
97 + 137639 = 137736
103 + 137633 = 137736
113 + 137623 = 137736

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 137,736 and was likely granted around 1872.

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