Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30146, here are decompositions:

7 + 30139 = 30146
13 + 30133 = 30146
37 + 30109 = 30146
43 + 30103 = 30146
157 + 29989 = 30146
163 + 29983 = 30146
199 + 29947 = 30146
229 + 29917 = 30146

Showing the first eight; more decompositions exist.
