Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76728, here are decompositions:

11 + 76717 = 76728
31 + 76697 = 76728
61 + 76667 = 76728
79 + 76649 = 76728
97 + 76631 = 76728
131 + 76597 = 76728
149 + 76579 = 76728
167 + 76561 = 76728

Showing the first eight; more decompositions exist.
