Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567654, here are decompositions:
- 5 + 31567649 = 31567654
- 11 + 31567643 = 31567654
- 17 + 31567637 = 31567654
- 101 + 31567553 = 31567654
- 227 + 31567427 = 31567654
- 257 + 31567397 = 31567654
- 383 + 31567271 = 31567654
- 563 + 31567091 = 31567654
Showing the first eight; more decompositions exist.
