Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30798, here are decompositions:

17 + 30781 = 30798
41 + 30757 = 30798
71 + 30727 = 30798
101 + 30697 = 30798
109 + 30689 = 30798
127 + 30671 = 30798
137 + 30661 = 30798
149 + 30649 = 30798

Showing the first eight; more decompositions exist.
