Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101390, here are decompositions:
- 7 + 101383 = 101390
- 13 + 101377 = 101390
- 31 + 101359 = 101390
- 43 + 101347 = 101390
- 67 + 101323 = 101390
- 97 + 101293 = 101390
- 103 + 101287 = 101390
- 109 + 101281 = 101390
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 101,390 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
