Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87732, here are decompositions:
- 11 + 87721 = 87732
- 13 + 87719 = 87732
- 31 + 87701 = 87732
- 41 + 87691 = 87732
- 53 + 87679 = 87732
- 61 + 87671 = 87732
- 83 + 87649 = 87732
- 89 + 87643 = 87732
Showing the first eight; more decompositions exist.
