Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30516, here are decompositions:

7 + 30509 = 30516
19 + 30497 = 30516
23 + 30493 = 30516
47 + 30469 = 30516
67 + 30449 = 30516
89 + 30427 = 30516
113 + 30403 = 30516
127 + 30389 = 30516

Showing the first eight; more decompositions exist.
