Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550138, here are decompositions:

11 + 550127 = 550138
89 + 550049 = 550138
131 + 550007 = 550138
227 + 549911 = 550138
389 + 549749 = 550138
401 + 549737 = 550138
419 + 549719 = 550138
431 + 549707 = 550138

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 550,138 and was likely granted around 1895.

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