Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520188, here are decompositions:

37 + 520151 = 520188
59 + 520129 = 520188
157 + 520031 = 520188
167 + 520021 = 520188
191 + 519997 = 520188
199 + 519989 = 520188
241 + 519947 = 520188
257 + 519931 = 520188

Showing the first eight; more decompositions exist.
