Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616486, here are decompositions:
- 7 + 31616479 = 31616486
- 67 + 31616419 = 31616486
- 127 + 31616359 = 31616486
- 199 + 31616287 = 31616486
- 229 + 31616257 = 31616486
- 313 + 31616173 = 31616486
- 337 + 31616149 = 31616486
- 373 + 31616113 = 31616486
Showing the first eight; more decompositions exist.
