Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100312, here are decompositions:

41 + 100271 = 100312
263 + 100049 = 100312
269 + 100043 = 100312
293 + 100019 = 100312
383 + 99929 = 100312
389 + 99923 = 100312
431 + 99881 = 100312
479 + 99833 = 100312

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 100,312 and was likely granted around 1870.

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