Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007490, here are decompositions:
- 7 + 1007483 = 1007490
- 23 + 1007467 = 1007490
- 31 + 1007459 = 1007490
- 61 + 1007429 = 1007490
- 73 + 1007417 = 1007490
- 89 + 1007401 = 1007490
- 103 + 1007387 = 1007490
- 109 + 1007381 = 1007490
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 1,007,490 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
