Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616488, here are decompositions:
- 107 + 31616381 = 31616488
- 149 + 31616339 = 31616488
- 191 + 31616297 = 31616488
- 227 + 31616261 = 31616488
- 257 + 31616231 = 31616488
- 269 + 31616219 = 31616488
- 359 + 31616129 = 31616488
- 419 + 31616069 = 31616488
Showing the first eight; more decompositions exist.
