Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509654, here are decompositions:

7 + 509647 = 509654
31 + 509623 = 509654
73 + 509581 = 509654
97 + 509557 = 509654
241 + 509413 = 509654
337 + 509317 = 509654
367 + 509287 = 509654
373 + 509281 = 509654

Showing the first eight; more decompositions exist.
