Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507720, here are decompositions:

7 + 507713 = 507720
23 + 507697 = 507720
29 + 507691 = 507720
47 + 507673 = 507720
53 + 507667 = 507720
79 + 507641 = 507720
89 + 507631 = 507720
113 + 507607 = 507720

Showing the first eight; more decompositions exist.
