Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509550, here are decompositions:

7 + 509543 = 509550
29 + 509521 = 509550
37 + 509513 = 509550
73 + 509477 = 509550
101 + 509449 = 509550
109 + 509441 = 509550
137 + 509413 = 509550
157 + 509393 = 509550

Showing the first eight; more decompositions exist.
