Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031830, here are decompositions:

17 + 1031813 = 1031830
71 + 1031759 = 1031830
89 + 1031741 = 1031830
101 + 1031729 = 1031830
113 + 1031717 = 1031830
197 + 1031633 = 1031830
269 + 1031561 = 1031830
281 + 1031549 = 1031830

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 3, 1830 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1830-03-01 (DMMYYYY (Euro, single-digit day))
1830-10-03 (MMDYYYY (US, single-digit day))
1830-03-10 (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 1,031,830 and was likely granted around 1912.

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