Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524240, here are decompositions:
- 17 + 31524223 = 31524240
- 43 + 31524197 = 31524240
- 47 + 31524193 = 31524240
- 73 + 31524167 = 31524240
- 79 + 31524161 = 31524240
- 107 + 31524133 = 31524240
- 149 + 31524091 = 31524240
- 191 + 31524049 = 31524240
Showing the first eight; more decompositions exist.
