Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101250, here are decompositions:
- 29 + 101221 = 101250
- 41 + 101209 = 101250
- 43 + 101207 = 101250
- 47 + 101203 = 101250
- 53 + 101197 = 101250
- 67 + 101183 = 101250
- 89 + 101161 = 101250
- 101 + 101149 = 101250
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 101,250 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
