Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30160, here are decompositions:

23 + 30137 = 30160
41 + 30119 = 30160
47 + 30113 = 30160
71 + 30089 = 30160
89 + 30071 = 30160
101 + 30059 = 30160
113 + 30047 = 30160
131 + 30029 = 30160

Showing the first eight; more decompositions exist.
