Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509078, here are decompositions:

7 + 509071 = 509078
109 + 508969 = 509078
127 + 508951 = 509078
211 + 508867 = 509078
307 + 508771 = 509078
457 + 508621 = 509078
499 + 508579 = 509078
547 + 508531 = 509078

Showing the first eight; more decompositions exist.
