Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30812, here are decompositions:

3 + 30809 = 30812
31 + 30781 = 30812
109 + 30703 = 30812
151 + 30661 = 30812
163 + 30649 = 30812
181 + 30631 = 30812
283 + 30529 = 30812
409 + 30403 = 30812

Showing the first eight; more decompositions exist.
