Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76864, here are decompositions:

17 + 76847 = 76864
83 + 76781 = 76864
107 + 76757 = 76864
131 + 76733 = 76864
167 + 76697 = 76864
191 + 76673 = 76864
197 + 76667 = 76864
233 + 76631 = 76864

Showing the first eight; more decompositions exist.
