Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045490, here are decompositions:
- 3 + 1045487 = 1045490
- 67 + 1045423 = 1045490
- 79 + 1045411 = 1045490
- 97 + 1045393 = 1045490
- 181 + 1045309 = 1045490
- 307 + 1045183 = 1045490
- 337 + 1045153 = 1045490
- 367 + 1045123 = 1045490
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 1,045,490 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
