Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501630, here are decompositions:

7 + 501623 = 501630
13 + 501617 = 501630
29 + 501601 = 501630
37 + 501593 = 501630
53 + 501577 = 501630
67 + 501563 = 501630
127 + 501503 = 501630
137 + 501493 = 501630

Showing the first eight; more decompositions exist.
