Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30512, here are decompositions:

3 + 30509 = 30512
19 + 30493 = 30512
43 + 30469 = 30512
109 + 30403 = 30512
193 + 30319 = 30512
199 + 30313 = 30512
241 + 30271 = 30512
271 + 30241 = 30512

Showing the first eight; more decompositions exist.
