Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77160, here are decompositions:

7 + 77153 = 77160
19 + 77141 = 77160
23 + 77137 = 77160
59 + 77101 = 77160
67 + 77093 = 77160
79 + 77081 = 77160
113 + 77047 = 77160
131 + 77029 = 77160

Showing the first eight; more decompositions exist.
