Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78664, here are decompositions:

11 + 78653 = 78664
41 + 78623 = 78664
71 + 78593 = 78664
167 + 78497 = 78664
197 + 78467 = 78664
227 + 78437 = 78664
263 + 78401 = 78664
317 + 78347 = 78664

Showing the first eight; more decompositions exist.
