Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000778, here are decompositions:

109 + 1000669 = 1000778
127 + 1000651 = 1000778
139 + 1000639 = 1000778
157 + 1000621 = 1000778
199 + 1000579 = 1000778
241 + 1000537 = 1000778
271 + 1000507 = 1000778
349 + 1000429 = 1000778

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 1,000,778 and was likely granted around 1911.

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