Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76780, here are decompositions:

3 + 76777 = 76780
23 + 76757 = 76780
47 + 76733 = 76780
83 + 76697 = 76780
101 + 76679 = 76780
107 + 76673 = 76780
113 + 76667 = 76780
131 + 76649 = 76780

Showing the first eight; more decompositions exist.
