Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125240, here are decompositions:
- 19 + 125221 = 125240
- 43 + 125197 = 125240
- 109 + 125131 = 125240
- 127 + 125113 = 125240
- 139 + 125101 = 125240
- 211 + 125029 = 125240
- 223 + 125017 = 125240
- 331 + 124909 = 125240
Showing the first eight; more decompositions exist.
