Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042430, here are decompositions:

3 + 1042427 = 1042430
31 + 1042399 = 1042430
61 + 1042369 = 1042430
73 + 1042357 = 1042430
97 + 1042333 = 1042430
157 + 1042273 = 1042430
163 + 1042267 = 1042430
307 + 1042123 = 1042430

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 2430 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2430-04-01 (DMMYYYY (Euro, single-digit day))
2430-10-04 (MMDYYYY (US, single-digit day))
2430-04-10 (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 1,042,430 and was likely granted around 1912.

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