Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76786, here are decompositions:

5 + 76781 = 76786
29 + 76757 = 76786
53 + 76733 = 76786
89 + 76697 = 76786
107 + 76679 = 76786
113 + 76673 = 76786
137 + 76649 = 76786
179 + 76607 = 76786

Showing the first eight; more decompositions exist.
