Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990308, here are decompositions:
- 19 + 990289 = 990308
- 31 + 990277 = 990308
- 97 + 990211 = 990308
- 127 + 990181 = 990308
- 139 + 990169 = 990308
- 157 + 990151 = 990308
- 271 + 990037 = 990308
- 307 + 990001 = 990308
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 990,308 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
