Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508438, here are decompositions:

5 + 508433 = 508438
71 + 508367 = 508438
89 + 508349 = 508438
107 + 508331 = 508438
137 + 508301 = 508438
167 + 508271 = 508438
179 + 508259 = 508438
251 + 508187 = 508438

Showing the first eight; more decompositions exist.
