Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77682, here are decompositions:

23 + 77659 = 77682
41 + 77641 = 77682
61 + 77621 = 77682
71 + 77611 = 77682
109 + 77573 = 77682
113 + 77569 = 77682
131 + 77551 = 77682
139 + 77543 = 77682

Showing the first eight; more decompositions exist.
