Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103130, here are decompositions:

7 + 103123 = 103130
31 + 103099 = 103130
37 + 103093 = 103130
43 + 103087 = 103130
61 + 103069 = 103130
163 + 102967 = 103130
199 + 102931 = 103130
271 + 102859 = 103130

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 103,130 and was likely granted around 1870.

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