Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3688, here are decompositions:
- 11 + 3677 = 3688
- 17 + 3671 = 3688
- 29 + 3659 = 3688
- 71 + 3617 = 3688
- 107 + 3581 = 3688
- 131 + 3557 = 3688
- 149 + 3539 = 3688
- 197 + 3491 = 3688
Showing the first eight; more decompositions exist.
