Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015600, here are decompositions:

29 + 1015571 = 1015600
41 + 1015559 = 1015600
59 + 1015541 = 1015600
83 + 1015517 = 1015600
101 + 1015499 = 1015600
137 + 1015463 = 1015600
149 + 1015451 = 1015600
167 + 1015433 = 1015600

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 5600 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

5600-10-01 (MMDYYYY (US, single-digit day))
5600-01-10 (DDMYYYY (Euro, single-digit month))

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 1,015,600 and was likely granted around 1911.

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