Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508220, here are decompositions:

7 + 508213 = 508220
61 + 508159 = 508220
199 + 508021 = 508220
211 + 508009 = 508220
241 + 507979 = 508220
283 + 507937 = 508220
313 + 507907 = 508220
337 + 507883 = 508220

Showing the first eight; more decompositions exist.
