Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020556, here are decompositions:

137 + 1020419 = 1020556
149 + 1020407 = 1020556
167 + 1020389 = 1020556
227 + 1020329 = 1020556
263 + 1020293 = 1020556
419 + 1020137 = 1020556
443 + 1020113 = 1020556
479 + 1020077 = 1020556

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 0556 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0556-02-01 (DMMYYYY (Euro, single-digit day))
0556-10-02 (MMDYYYY (US, single-digit day))
0556-02-10 (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 1,020,556 and was likely granted around 1911.

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