Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509554, here are decompositions:

5 + 509549 = 509554
11 + 509543 = 509554
41 + 509513 = 509554
113 + 509441 = 509554
137 + 509417 = 509554
191 + 509363 = 509554
257 + 509297 = 509554
431 + 509123 = 509554

Showing the first eight; more decompositions exist.
