Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031998, here are decompositions:

17 + 1031981 = 1031998
167 + 1031831 = 1031998
239 + 1031759 = 1031998
257 + 1031741 = 1031998
269 + 1031729 = 1031998
281 + 1031717 = 1031998
389 + 1031609 = 1031998
449 + 1031549 = 1031998

Showing the first eight; more decompositions exist.

1998-03-10 (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 1,031,998 and was likely granted around 1912.

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