Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509494, here are decompositions:

17 + 509477 = 509494
53 + 509441 = 509494
101 + 509393 = 509494
131 + 509363 = 509494
197 + 509297 = 509494
347 + 509147 = 509494
431 + 509063 = 509494
467 + 509027 = 509494

Showing the first eight; more decompositions exist.
