Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023430, here are decompositions:

11 + 1023419 = 1023430
17 + 1023413 = 1023430
41 + 1023389 = 1023430
101 + 1023329 = 1023430
113 + 1023317 = 1023430
131 + 1023299 = 1023430
167 + 1023263 = 1023430
173 + 1023257 = 1023430

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

3430-02-01 (DMMYYYY (Euro, single-digit day))
3430-10-02 (MMDYYYY (US, single-digit day))
3430-02-10 (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 1,023,430 and was likely granted around 1912.

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