Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508420, here are decompositions:

47 + 508373 = 508420
53 + 508367 = 508420
71 + 508349 = 508420
89 + 508331 = 508420
149 + 508271 = 508420
191 + 508229 = 508420
197 + 508223 = 508420
233 + 508187 = 508420

Showing the first eight; more decompositions exist.
