Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77866, here are decompositions:

3 + 77863 = 77866
17 + 77849 = 77866
53 + 77813 = 77866
83 + 77783 = 77866
167 + 77699 = 77866
179 + 77687 = 77866
293 + 77573 = 77866
317 + 77549 = 77866

Showing the first eight; more decompositions exist.
