Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616210, here are decompositions:
- 37 + 31616173 = 31616210
- 61 + 31616149 = 31616210
- 97 + 31616113 = 31616210
- 151 + 31616059 = 31616210
- 163 + 31616047 = 31616210
- 193 + 31616017 = 31616210
- 211 + 31615999 = 31616210
- 499 + 31615711 = 31616210
Showing the first eight; more decompositions exist.
