Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77690, here are decompositions:

3 + 77687 = 77690
31 + 77659 = 77690
43 + 77647 = 77690
73 + 77617 = 77690
79 + 77611 = 77690
103 + 77587 = 77690
127 + 77563 = 77690
139 + 77551 = 77690

Showing the first eight; more decompositions exist.
