Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001490, here are decompositions:
- 23 + 1001467 = 1001490
- 31 + 1001459 = 1001490
- 43 + 1001447 = 1001490
- 59 + 1001431 = 1001490
- 79 + 1001411 = 1001490
- 89 + 1001401 = 1001490
- 101 + 1001389 = 1001490
- 103 + 1001387 = 1001490
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 1,001,490 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
