Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30738, here are decompositions:

11 + 30727 = 30738
31 + 30707 = 30738
41 + 30697 = 30738
61 + 30677 = 30738
67 + 30671 = 30738
89 + 30649 = 30738
101 + 30637 = 30738
107 + 30631 = 30738

Showing the first eight; more decompositions exist.
