Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30170, here are decompositions:

31 + 30139 = 30170
37 + 30133 = 30170
61 + 30109 = 30170
67 + 30103 = 30170
73 + 30097 = 30170
79 + 30091 = 30170
157 + 30013 = 30170
181 + 29989 = 30170

Showing the first eight; more decompositions exist.
