Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15708, here are decompositions:
- 29 + 15679 = 15708
- 37 + 15671 = 15708
- 41 + 15667 = 15708
- 47 + 15661 = 15708
- 59 + 15649 = 15708
- 61 + 15647 = 15708
- 67 + 15641 = 15708
- 79 + 15629 = 15708
Showing the first eight; more decompositions exist.
