Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538156, here are decompositions:

5 + 538151 = 538156
29 + 538127 = 538156
83 + 538073 = 538156
107 + 538049 = 538156
137 + 538019 = 538156
257 + 537899 = 538156
383 + 537773 = 538156
557 + 537599 = 538156

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 538,156 and was likely granted around 1894.

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