Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103156, here are decompositions:

89 + 103067 = 103156
107 + 103049 = 103156
113 + 103043 = 103156
149 + 103007 = 103156
173 + 102983 = 103156
227 + 102929 = 103156
359 + 102797 = 103156
479 + 102677 = 103156

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 103,156 and was likely granted around 1870.

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