Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524748, here are decompositions:
- 71 + 31524677 = 31524748
- 107 + 31524641 = 31524748
- 179 + 31524569 = 31524748
- 239 + 31524509 = 31524748
- 491 + 31524257 = 31524748
- 587 + 31524161 = 31524748
- 641 + 31524107 = 31524748
- 701 + 31524047 = 31524748
Showing the first eight; more decompositions exist.
