Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616, here are decompositions:
- 43 + 31573 = 31616
- 73 + 31543 = 31616
- 103 + 31513 = 31616
- 127 + 31489 = 31616
- 139 + 31477 = 31616
- 223 + 31393 = 31616
- 229 + 31387 = 31616
- 283 + 31333 = 31616
Showing the first eight; more decompositions exist.
