Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30162, here are decompositions:

23 + 30139 = 30162
29 + 30133 = 30162
43 + 30119 = 30162
53 + 30109 = 30162
59 + 30103 = 30162
71 + 30091 = 30162
73 + 30089 = 30162
103 + 30059 = 30162

Showing the first eight; more decompositions exist.
