Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617548, here are decompositions:
- 19 + 31617529 = 31617548
- 139 + 31617409 = 31617548
- 349 + 31617199 = 31617548
- 367 + 31617181 = 31617548
- 499 + 31617049 = 31617548
- 619 + 31616929 = 31617548
- 631 + 31616917 = 31617548
- 661 + 31616887 = 31617548
Showing the first eight; more decompositions exist.
