Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507816, here are decompositions:

7 + 507809 = 507816
13 + 507803 = 507816
19 + 507797 = 507816
37 + 507779 = 507816
59 + 507757 = 507816
73 + 507743 = 507816
97 + 507719 = 507816
103 + 507713 = 507816

Showing the first eight; more decompositions exist.
