Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023790, here are decompositions:

59 + 1023731 = 1023790
71 + 1023719 = 1023790
137 + 1023653 = 1023790
233 + 1023557 = 1023790
239 + 1023551 = 1023790
269 + 1023521 = 1023790
401 + 1023389 = 1023790
461 + 1023329 = 1023790

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

3790-02-01 (DMMYYYY (Euro, single-digit day))
3790-10-02 (MMDYYYY (US, single-digit day))
3790-02-10 (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 1,023,790 and was likely granted around 1912.

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