Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30130, here are decompositions:

11 + 30119 = 30130
17 + 30113 = 30130
41 + 30089 = 30130
59 + 30071 = 30130
71 + 30059 = 30130
83 + 30047 = 30130
101 + 30029 = 30130
251 + 29879 = 30130

Showing the first eight; more decompositions exist.
