Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77208, here are decompositions:

7 + 77201 = 77208
17 + 77191 = 77208
37 + 77171 = 77208
41 + 77167 = 77208
67 + 77141 = 77208
71 + 77137 = 77208
107 + 77101 = 77208
127 + 77081 = 77208

Showing the first eight; more decompositions exist.
