Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148750, here are decompositions:
- 3 + 148747 = 148750
- 23 + 148727 = 148750
- 29 + 148721 = 148750
- 59 + 148691 = 148750
- 83 + 148667 = 148750
- 233 + 148517 = 148750
- 281 + 148469 = 148750
- 293 + 148457 = 148750
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 148,750 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
