Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104278, here are decompositions:

47 + 104231 = 104278
71 + 104207 = 104278
131 + 104147 = 104278
191 + 104087 = 104278
257 + 104021 = 104278
269 + 104009 = 104278
281 + 103997 = 104278
311 + 103967 = 104278

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 104,278 and was likely granted around 1870.

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