Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30664, here are decompositions:

3 + 30661 = 30664
71 + 30593 = 30664
107 + 30557 = 30664
167 + 30497 = 30664
173 + 30491 = 30664
197 + 30467 = 30664
233 + 30431 = 30664
317 + 30347 = 30664

Showing the first eight; more decompositions exist.
