Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124628, here are decompositions:
- 61 + 124567 = 124628
- 67 + 124561 = 124628
- 139 + 124489 = 124628
- 151 + 124477 = 124628
- 157 + 124471 = 124628
- 181 + 124447 = 124628
- 199 + 124429 = 124628
- 277 + 124351 = 124628
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 124,628 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
