Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055580, here are decompositions:

13 + 1055567 = 1055580
37 + 1055543 = 1055580
79 + 1055501 = 1055580
109 + 1055471 = 1055580
151 + 1055429 = 1055580
157 + 1055423 = 1055580
167 + 1055413 = 1055580
173 + 1055407 = 1055580

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 1,055,580 and was likely granted around 1912.

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