Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101490, here are decompositions:
- 7 + 101483 = 101490
- 13 + 101477 = 101490
- 23 + 101467 = 101490
- 41 + 101449 = 101490
- 61 + 101429 = 101490
- 71 + 101419 = 101490
- 79 + 101411 = 101490
- 107 + 101383 = 101490
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 101,490 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
