Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532688, here are decompositions:
- 29 + 31532659 = 31532688
- 101 + 31532587 = 31532688
- 107 + 31532581 = 31532688
- 137 + 31532551 = 31532688
- 149 + 31532539 = 31532688
- 167 + 31532521 = 31532688
- 181 + 31532507 = 31532688
- 191 + 31532497 = 31532688
Showing the first eight; more decompositions exist.
