Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30218, here are decompositions:

7 + 30211 = 30218
31 + 30187 = 30218
37 + 30181 = 30218
79 + 30139 = 30218
109 + 30109 = 30218
127 + 30091 = 30218
229 + 29989 = 30218
271 + 29947 = 30218

Showing the first eight; more decompositions exist.
