Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508228, here are decompositions:

5 + 508223 = 508228
41 + 508187 = 508228
131 + 508097 = 508228
137 + 508091 = 508228
191 + 508037 = 508228
257 + 507971 = 508228
311 + 507917 = 508228
389 + 507839 = 508228

Showing the first eight; more decompositions exist.
