Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122900, here are decompositions:

13 + 122887 = 122900
31 + 122869 = 122900
61 + 122839 = 122900
67 + 122833 = 122900
73 + 122827 = 122900
139 + 122761 = 122900
157 + 122743 = 122900
181 + 122719 = 122900

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 122,900 and was likely granted around 1871.

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