Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509618, here are decompositions:

37 + 509581 = 509618
61 + 509557 = 509618
97 + 509521 = 509618
229 + 509389 = 509618
331 + 509287 = 509618
337 + 509281 = 509618
379 + 509239 = 509618
397 + 509221 = 509618

Showing the first eight; more decompositions exist.
