Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047500, here are decompositions:

31 + 1047469 = 1047500
109 + 1047391 = 1047500
127 + 1047373 = 1047500
193 + 1047307 = 1047500
211 + 1047289 = 1047500
229 + 1047271 = 1047500
271 + 1047229 = 1047500
367 + 1047133 = 1047500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 7500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

7500-04-01 (DMMYYYY (Euro, single-digit day))
7500-10-04 (MMDYYYY (US, single-digit day))
7500-04-10 (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 1,047,500 and was likely granted around 1912.

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