Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510218, here are decompositions:

19 + 510199 = 510218
61 + 510157 = 510218
97 + 510121 = 510218
139 + 510079 = 510218
151 + 510067 = 510218
157 + 510061 = 510218
211 + 510007 = 510218
229 + 509989 = 510218

Showing the first eight; more decompositions exist.
