Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508188, here are decompositions:

17 + 508171 = 508188
29 + 508159 = 508188
59 + 508129 = 508188
97 + 508091 = 508188
101 + 508087 = 508188
151 + 508037 = 508188
167 + 508021 = 508188
179 + 508009 = 508188

Showing the first eight; more decompositions exist.
