Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045272, here are decompositions:

31 + 1045241 = 1045272
43 + 1045229 = 1045272
73 + 1045199 = 1045272
79 + 1045193 = 1045272
89 + 1045183 = 1045272
149 + 1045123 = 1045272
191 + 1045081 = 1045272
211 + 1045061 = 1045272

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 5272 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

5272-04-01 (DMMYYYY (Euro, single-digit day))
5272-10-04 (MMDYYYY (US, single-digit day))
5272-04-10 (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 1,045,272 and was likely granted around 1912.

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