Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101240, here are decompositions:
- 19 + 101221 = 101240
- 31 + 101209 = 101240
- 37 + 101203 = 101240
- 43 + 101197 = 101240
- 67 + 101173 = 101240
- 79 + 101161 = 101240
- 127 + 101113 = 101240
- 151 + 101089 = 101240
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 101,240 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
