Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77620, here are decompositions:

3 + 77617 = 77620
29 + 77591 = 77620
47 + 77573 = 77620
71 + 77549 = 77620
107 + 77513 = 77620
131 + 77489 = 77620
149 + 77471 = 77620
173 + 77447 = 77620

Showing the first eight; more decompositions exist.
