Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501216, here are decompositions:

7 + 501209 = 501216
13 + 501203 = 501216
19 + 501197 = 501216
29 + 501187 = 501216
43 + 501173 = 501216
59 + 501157 = 501216
83 + 501133 = 501216
113 + 501103 = 501216

Showing the first eight; more decompositions exist.
