Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106990, here are decompositions:
- 11 + 106979 = 106990
- 29 + 106961 = 106990
- 41 + 106949 = 106990
- 53 + 106937 = 106990
- 83 + 106907 = 106990
- 113 + 106877 = 106990
- 131 + 106859 = 106990
- 137 + 106853 = 106990
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 106,990 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
