Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500398, here are decompositions:

5 + 500393 = 500398
29 + 500369 = 500398
149 + 500249 = 500398
167 + 500231 = 500398
389 + 500009 = 500398
419 + 499979 = 500398
617 + 499781 = 500398
659 + 499739 = 500398

Showing the first eight; more decompositions exist.
