Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152140, here are decompositions:

17 + 152123 = 152140
29 + 152111 = 152140
47 + 152093 = 152140
59 + 152081 = 152140
101 + 152039 = 152140
113 + 152027 = 152140
137 + 152003 = 152140
173 + 151967 = 152140

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 152,140 and was likely granted around 1873.

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