Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544372, here are decompositions:
- 61 + 31544311 = 31544372
- 151 + 31544221 = 31544372
- 193 + 31544179 = 31544372
- 241 + 31544131 = 31544372
- 283 + 31544089 = 31544372
- 331 + 31544041 = 31544372
- 499 + 31543873 = 31544372
- 661 + 31543711 = 31544372
Showing the first eight; more decompositions exist.
