Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509228, here are decompositions:

7 + 509221 = 509228
79 + 509149 = 509228
127 + 509101 = 509228
157 + 509071 = 509228
241 + 508987 = 509228
271 + 508957 = 509228
277 + 508951 = 509228
439 + 508789 = 509228

Showing the first eight; more decompositions exist.
