Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30708, here are decompositions:

5 + 30703 = 30708
11 + 30697 = 30708
19 + 30689 = 30708
31 + 30677 = 30708
37 + 30671 = 30708
47 + 30661 = 30708
59 + 30649 = 30708
71 + 30637 = 30708

Showing the first eight; more decompositions exist.
