Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507828, here are decompositions:

7 + 507821 = 507828
19 + 507809 = 507828
31 + 507797 = 507828
47 + 507781 = 507828
71 + 507757 = 507828
109 + 507719 = 507828
131 + 507697 = 507828
137 + 507691 = 507828

Showing the first eight; more decompositions exist.
