Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509680, here are decompositions:

47 + 509633 = 509680
89 + 509591 = 509680
107 + 509573 = 509680
131 + 509549 = 509680
137 + 509543 = 509680
167 + 509513 = 509680
239 + 509441 = 509680
251 + 509429 = 509680

Showing the first eight; more decompositions exist.
