Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100308, here are decompositions:

11 + 100297 = 100308
17 + 100291 = 100308
29 + 100279 = 100308
37 + 100271 = 100308
41 + 100267 = 100308
71 + 100237 = 100308
101 + 100207 = 100308
139 + 100169 = 100308

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 100,308 and was likely granted around 1870.

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