Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30220, here are decompositions:

17 + 30203 = 30220
23 + 30197 = 30220
59 + 30161 = 30220
83 + 30137 = 30220
101 + 30119 = 30220
107 + 30113 = 30220
131 + 30089 = 30220
149 + 30071 = 30220

Showing the first eight; more decompositions exist.
