Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015864, here are decompositions:

11 + 1015853 = 1015864
41 + 1015823 = 1015864
137 + 1015727 = 1015864
167 + 1015697 = 1015864
173 + 1015691 = 1015864
263 + 1015601 = 1015864
293 + 1015571 = 1015864
347 + 1015517 = 1015864

Showing the first eight; more decompositions exist.

Other possible interpretations (2)

5864-10-01 (MMDYYYY (US, single-digit day))
5864-01-10 (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 1,015,864 and was likely granted around 1911.

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