Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15512, here are decompositions:
- 19 + 15493 = 15512
- 61 + 15451 = 15512
- 73 + 15439 = 15512
- 139 + 15373 = 15512
- 151 + 15361 = 15512
- 163 + 15349 = 15512
- 181 + 15331 = 15512
- 193 + 15319 = 15512
Showing the first eight; more decompositions exist.
