Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15732, here are decompositions:
- 5 + 15727 = 15732
- 53 + 15679 = 15732
- 61 + 15671 = 15732
- 71 + 15661 = 15732
- 83 + 15649 = 15732
- 89 + 15643 = 15732
- 103 + 15629 = 15732
- 113 + 15619 = 15732
Showing the first eight; more decompositions exist.
