Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018804, here are decompositions:

41 + 1018763 = 1018804
71 + 1018733 = 1018804
107 + 1018697 = 1018804
131 + 1018673 = 1018804
191 + 1018613 = 1018804
383 + 1018421 = 1018804
467 + 1018337 = 1018804
491 + 1018313 = 1018804

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 1,018,804 and was likely granted around 1911.

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