Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000018, here are decompositions:

59 + 999959 = 1000018
101 + 999917 = 1000018
269 + 999749 = 1000018
347 + 999671 = 1000018
419 + 999599 = 1000018
587 + 999431 = 1000018
641 + 999377 = 1000018
647 + 999371 = 1000018

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 1,000,018 and was likely granted around 1911.

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