Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3712, here are decompositions:
- 3 + 3709 = 3712
- 11 + 3701 = 3712
- 41 + 3671 = 3712
- 53 + 3659 = 3712
- 89 + 3623 = 3712
- 131 + 3581 = 3712
- 173 + 3539 = 3712
- 179 + 3533 = 3712
Showing the first eight; more decompositions exist.
