Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608030, here are decompositions:

17 + 31608013 = 31608030
59 + 31607971 = 31608030
61 + 31607969 = 31608030
109 + 31607921 = 31608030
127 + 31607903 = 31608030
163 + 31607867 = 31608030
173 + 31607857 = 31608030
191 + 31607839 = 31608030

Showing the first eight; more decompositions exist.
