Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506826, here are decompositions:
- 3 + 31506823 = 31506826
- 5 + 31506821 = 31506826
- 17 + 31506809 = 31506826
- 83 + 31506743 = 31506826
- 107 + 31506719 = 31506826
- 137 + 31506689 = 31506826
- 149 + 31506677 = 31506826
- 227 + 31506599 = 31506826
Showing the first eight; more decompositions exist.
