Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77722, here are decompositions:

3 + 77719 = 77722
11 + 77711 = 77722
23 + 77699 = 77722
41 + 77681 = 77722
101 + 77621 = 77722
131 + 77591 = 77722
149 + 77573 = 77722
173 + 77549 = 77722

Showing the first eight; more decompositions exist.
