Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616864, here are decompositions:
- 7 + 31616857 = 31616864
- 157 + 31616707 = 31616864
- 193 + 31616671 = 31616864
- 241 + 31616623 = 31616864
- 463 + 31616401 = 31616864
- 577 + 31616287 = 31616864
- 607 + 31616257 = 31616864
- 613 + 31616251 = 31616864
Showing the first eight; more decompositions exist.
