Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77320, here are decompositions:

3 + 77317 = 77320
29 + 77291 = 77320
41 + 77279 = 77320
53 + 77267 = 77320
59 + 77261 = 77320
71 + 77249 = 77320
83 + 77237 = 77320
107 + 77213 = 77320

Showing the first eight; more decompositions exist.
