Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100778, here are decompositions:

31 + 100747 = 100778
37 + 100741 = 100778
79 + 100699 = 100778
109 + 100669 = 100778
157 + 100621 = 100778
229 + 100549 = 100778
241 + 100537 = 100778
277 + 100501 = 100778

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 100,778 and was likely granted around 1870.

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