Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30172, here are decompositions:

3 + 30169 = 30172
11 + 30161 = 30172
53 + 30119 = 30172
59 + 30113 = 30172
83 + 30089 = 30172
101 + 30071 = 30172
113 + 30059 = 30172
251 + 29921 = 30172

Showing the first eight; more decompositions exist.
