Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154656, here are decompositions:

13 + 154643 = 154656
37 + 154619 = 154656
43 + 154613 = 154656
67 + 154589 = 154656
83 + 154573 = 154656
113 + 154543 = 154656
163 + 154493 = 154656
197 + 154459 = 154656

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 154,656 and was likely granted around 1873.

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