Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155010, here are decompositions:

7 + 155003 = 155010
19 + 154991 = 155010
29 + 154981 = 155010
67 + 154943 = 155010
73 + 154937 = 155010
83 + 154927 = 155010
113 + 154897 = 155010
127 + 154883 = 155010

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 155,010 and was likely granted around 1873.

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