Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77662, here are decompositions:

3 + 77659 = 77662
41 + 77621 = 77662
71 + 77591 = 77662
89 + 77573 = 77662
113 + 77549 = 77662
149 + 77513 = 77662
173 + 77489 = 77662
191 + 77471 = 77662

Showing the first eight; more decompositions exist.
