Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170490, here are decompositions:
- 7 + 170483 = 170490
- 17 + 170473 = 170490
- 43 + 170447 = 170490
- 97 + 170393 = 170490
- 101 + 170389 = 170490
- 107 + 170383 = 170490
- 127 + 170363 = 170490
- 137 + 170353 = 170490
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 170,490 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
