Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77650, here are decompositions:

3 + 77647 = 77650
29 + 77621 = 77650
59 + 77591 = 77650
101 + 77549 = 77650
107 + 77543 = 77650
137 + 77513 = 77650
173 + 77477 = 77650
179 + 77471 = 77650

Showing the first eight; more decompositions exist.
