Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15552, here are decompositions:
- 11 + 15541 = 15552
- 41 + 15511 = 15552
- 59 + 15493 = 15552
- 79 + 15473 = 15552
- 101 + 15451 = 15552
- 109 + 15443 = 15552
- 113 + 15439 = 15552
- 139 + 15413 = 15552
Showing the first eight; more decompositions exist.
