Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031198, here are decompositions:

37 + 1031161 = 1031198
61 + 1031137 = 1031198
79 + 1031119 = 1031198
151 + 1031047 = 1031198
211 + 1030987 = 1031198
241 + 1030957 = 1031198
331 + 1030867 = 1031198
367 + 1030831 = 1031198

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

1198-03-01 (DMMYYYY (Euro, single-digit day))
1198-10-03 (MMDYYYY (US, single-digit day))
1198-03-10 (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 1,031,198 and was likely granted around 1912.

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