Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474412, here are decompositions:
- 61 + 31474351 = 31474412
- 163 + 31474249 = 31474412
- 199 + 31474213 = 31474412
- 241 + 31474171 = 31474412
- 271 + 31474141 = 31474412
- 283 + 31474129 = 31474412
- 379 + 31474033 = 31474412
- 421 + 31473991 = 31474412
Showing the first eight; more decompositions exist.
