Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617216, here are decompositions:
- 17 + 31617199 = 31617216
- 67 + 31617149 = 31617216
- 83 + 31617133 = 31617216
- 139 + 31617077 = 31617216
- 167 + 31617049 = 31617216
- 193 + 31617023 = 31617216
- 229 + 31616987 = 31617216
- 283 + 31616933 = 31617216
Showing the first eight; more decompositions exist.
