Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616870, here are decompositions:
- 13 + 31616857 = 31616870
- 31 + 31616839 = 31616870
- 97 + 31616773 = 31616870
- 163 + 31616707 = 31616870
- 193 + 31616677 = 31616870
- 199 + 31616671 = 31616870
- 223 + 31616647 = 31616870
- 331 + 31616539 = 31616870
Showing the first eight; more decompositions exist.
