Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543784, here are decompositions:
- 7 + 31543777 = 31543784
- 61 + 31543723 = 31543784
- 73 + 31543711 = 31543784
- 241 + 31543543 = 31543784
- 331 + 31543453 = 31543784
- 541 + 31543243 = 31543784
- 577 + 31543207 = 31543784
- 907 + 31542877 = 31543784
Showing the first eight; more decompositions exist.
