Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15632, here are decompositions:
- 3 + 15629 = 15632
- 13 + 15619 = 15632
- 31 + 15601 = 15632
- 73 + 15559 = 15632
- 139 + 15493 = 15632
- 181 + 15451 = 15632
- 193 + 15439 = 15632
- 241 + 15391 = 15632
Showing the first eight; more decompositions exist.
