Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30538, here are decompositions:

29 + 30509 = 30538
41 + 30497 = 30538
47 + 30491 = 30538
71 + 30467 = 30538
89 + 30449 = 30538
107 + 30431 = 30538
149 + 30389 = 30538
191 + 30347 = 30538

Showing the first eight; more decompositions exist.
