Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105090, here are decompositions:
- 19 + 105071 = 105090
- 53 + 105037 = 105090
- 59 + 105031 = 105090
- 67 + 105023 = 105090
- 71 + 105019 = 105090
- 103 + 104987 = 105090
- 131 + 104959 = 105090
- 137 + 104953 = 105090
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 105.090 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
