Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027660, here are decompositions:

17 + 1027643 = 1027660
47 + 1027613 = 1027660
113 + 1027547 = 1027660
167 + 1027493 = 1027660
173 + 1027487 = 1027660
233 + 1027427 = 1027660
239 + 1027421 = 1027660
251 + 1027409 = 1027660

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 1,027,660 and was likely granted around 1912.

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