Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023000, here are decompositions:
- 19 + 1022981 = 1023000
- 23 + 1022977 = 1023000
- 37 + 1022963 = 1023000
- 67 + 1022933 = 1023000
- 71 + 1022929 = 1023000
- 89 + 1022911 = 1023000
- 101 + 1022899 = 1023000
- 109 + 1022891 = 1023000
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,023,000 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
