Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015320, here are decompositions:

11 + 1015309 = 1015320
43 + 1015277 = 1015320
113 + 1015207 = 1015320
149 + 1015171 = 1015320
157 + 1015163 = 1015320
181 + 1015139 = 1015320
193 + 1015127 = 1015320
197 + 1015123 = 1015320

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5320 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

5320-10-01 (MMDYYYY (US, single-digit day))
5320-01-10 (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 1,015,320 and was likely granted around 1911.

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