Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042918, here are decompositions:

17 + 1042901 = 1042918
89 + 1042829 = 1042918
137 + 1042781 = 1042918
311 + 1042607 = 1042918
347 + 1042571 = 1042918
389 + 1042529 = 1042918
431 + 1042487 = 1042918
449 + 1042469 = 1042918

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2918 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2918-04-01 (DMMYYYY (Euro, single-digit day))
2918-10-04 (MMDYYYY (US, single-digit day))
2918-04-10 (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 1,042,918 and was likely granted around 1912.

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