Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509028, here are decompositions:

5 + 509023 = 509028
41 + 508987 = 509028
59 + 508969 = 509028
67 + 508961 = 509028
71 + 508957 = 509028
97 + 508931 = 509028
109 + 508919 = 509028
127 + 508901 = 509028

Showing the first eight; more decompositions exist.
