Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015430, here are decompositions:

7 + 1015423 = 1015430
61 + 1015369 = 1015430
67 + 1015363 = 1015430
223 + 1015207 = 1015430
271 + 1015159 = 1015430
307 + 1015123 = 1015430
337 + 1015093 = 1015430
349 + 1015081 = 1015430

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 5430 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

5430-10-01 (MMDYYYY (US, single-digit day))
5430-01-10 (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 1,015,430 and was likely granted around 1911.

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