Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542250, here are decompositions:
- 17 + 31542233 = 31542250
- 53 + 31542197 = 31542250
- 101 + 31542149 = 31542250
- 137 + 31542113 = 31542250
- 167 + 31542083 = 31542250
- 227 + 31542023 = 31542250
- 239 + 31542011 = 31542250
- 269 + 31541981 = 31542250
Showing the first eight; more decompositions exist.
