Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018616, here are decompositions:

3 + 1018613 = 1018616
73 + 1018543 = 1018616
103 + 1018513 = 1018616
127 + 1018489 = 1018616
139 + 1018477 = 1018616
307 + 1018309 = 1018616
409 + 1018207 = 1018616
439 + 1018177 = 1018616

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 1,018,616 and was likely granted around 1911.

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