Goldbach decomposition

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.
