Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061440, here are decompositions:

47 + 1061393 = 1061440
167 + 1061273 = 1061440
179 + 1061261 = 1061440
251 + 1061189 = 1061440
269 + 1061171 = 1061440
311 + 1061129 = 1061440
353 + 1061087 = 1061440
383 + 1061057 = 1061440

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 1,061,440 and was likely granted around 1912.

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