Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508458, here are decompositions:

7 + 508451 = 508458
19 + 508439 = 508458
109 + 508349 = 508458
127 + 508331 = 508458
131 + 508327 = 508458
157 + 508301 = 508458
199 + 508259 = 508458
229 + 508229 = 508458

Showing the first eight; more decompositions exist.
