Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047440, here are decompositions:

61 + 1047379 = 1047440
67 + 1047373 = 1047440
73 + 1047367 = 1047440
127 + 1047313 = 1047440
151 + 1047289 = 1047440
157 + 1047283 = 1047440
193 + 1047247 = 1047440
211 + 1047229 = 1047440

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 1,047,440 and was likely granted around 1912.

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