Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023130, here are decompositions:

23 + 1023107 = 1023130
29 + 1023101 = 1023130
47 + 1023083 = 1023130
83 + 1023047 = 1023130
89 + 1023041 = 1023130
149 + 1022981 = 1023130
167 + 1022963 = 1023130
197 + 1022933 = 1023130

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 3130 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

3130-02-01 (DMMYYYY (Euro, single-digit day))
3130-10-02 (MMDYYYY (US, single-digit day))
3130-02-10 (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 1,023,130 and was likely granted around 1912.

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