Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501218, here are decompositions:

31 + 501187 = 501218
61 + 501157 = 501218
79 + 501139 = 501218
97 + 501121 = 501218
181 + 501037 = 501218
199 + 501019 = 501218
241 + 500977 = 501218
271 + 500947 = 501218

Showing the first eight; more decompositions exist.
