Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146990, here are decompositions:
- 3 + 146987 = 146990
- 7 + 146983 = 146990
- 13 + 146977 = 146990
- 37 + 146953 = 146990
- 73 + 146917 = 146990
- 97 + 146893 = 146990
- 157 + 146833 = 146990
- 223 + 146767 = 146990
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 146,990 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
