Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524246, here are decompositions:
- 23 + 31524223 = 31524246
- 53 + 31524193 = 31524246
- 79 + 31524167 = 31524246
- 113 + 31524133 = 31524246
- 139 + 31524107 = 31524246
- 197 + 31524049 = 31524246
- 199 + 31524047 = 31524246
- 223 + 31524023 = 31524246
Showing the first eight; more decompositions exist.
