Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151020, here are decompositions:

7 + 151013 = 151020
11 + 151009 = 151020
13 + 151007 = 151020
29 + 150991 = 151020
31 + 150989 = 151020
41 + 150979 = 151020
53 + 150967 = 151020
59 + 150961 = 151020

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 151,020 and was likely granted around 1873.

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