Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616458, here are decompositions:
- 47 + 31616411 = 31616458
- 89 + 31616369 = 31616458
- 131 + 31616327 = 31616458
- 197 + 31616261 = 31616458
- 227 + 31616231 = 31616458
- 239 + 31616219 = 31616458
- 389 + 31616069 = 31616458
- 449 + 31616009 = 31616458
Showing the first eight; more decompositions exist.
