Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100390, here are decompositions:
- 11 + 100379 = 100390
- 29 + 100361 = 100390
- 47 + 100343 = 100390
- 197 + 100193 = 100390
- 239 + 100151 = 100390
- 281 + 100109 = 100390
- 347 + 100043 = 100390
- 401 + 99989 = 100390
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 100,390 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
