Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018384, here are decompositions:

47 + 1018337 = 1018384
71 + 1018313 = 1018384
83 + 1018301 = 1018384
113 + 1018271 = 1018384
131 + 1018253 = 1018384
137 + 1018247 = 1018384
167 + 1018217 = 1018384
293 + 1018091 = 1018384

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 8384 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

8384-10-01 (MMDYYYY (US, single-digit day))
8384-01-10 (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 1,018,384 and was likely granted around 1911.

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