Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509822, here are decompositions:

163 + 509659 = 509822
199 + 509623 = 509822
241 + 509581 = 509822
373 + 509449 = 509822
409 + 509413 = 509822
433 + 509389 = 509822
463 + 509359 = 509822
541 + 509281 = 509822

Showing the first eight; more decompositions exist.
