Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509548, here are decompositions:

5 + 509543 = 509548
71 + 509477 = 509548
107 + 509441 = 509548
131 + 509417 = 509548
251 + 509297 = 509548
401 + 509147 = 509548
461 + 509087 = 509548
521 + 509027 = 509548

Showing the first eight; more decompositions exist.
