Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045790, here are decompositions:

61 + 1045729 = 1045790
127 + 1045663 = 1045790
139 + 1045651 = 1045790
157 + 1045633 = 1045790
241 + 1045549 = 1045790
283 + 1045507 = 1045790
367 + 1045423 = 1045790
379 + 1045411 = 1045790

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

5790-04-01 (DMMYYYY (Euro, single-digit day))
5790-10-04 (MMDYYYY (US, single-digit day))
5790-04-10 (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 1,045,790 and was likely granted around 1912.

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