Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524080, here are decompositions:
- 31 + 31524049 = 31524080
- 37 + 31524043 = 31524080
- 67 + 31524013 = 31524080
- 127 + 31523953 = 31524080
- 139 + 31523941 = 31524080
- 163 + 31523917 = 31524080
- 199 + 31523881 = 31524080
- 229 + 31523851 = 31524080
Showing the first eight; more decompositions exist.
