Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31654, here are decompositions:
- 5 + 31649 = 31654
- 11 + 31643 = 31654
- 47 + 31607 = 31654
- 53 + 31601 = 31654
- 71 + 31583 = 31654
- 107 + 31547 = 31654
- 113 + 31541 = 31654
- 137 + 31517 = 31654
Showing the first eight; more decompositions exist.
