Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30758, here are decompositions:

31 + 30727 = 30758
61 + 30697 = 30758
97 + 30661 = 30758
109 + 30649 = 30758
127 + 30631 = 30758
181 + 30577 = 30758
199 + 30559 = 30758
229 + 30529 = 30758

Showing the first eight; more decompositions exist.
