Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77120, here are decompositions:

19 + 77101 = 77120
73 + 77047 = 77120
79 + 77041 = 77120
97 + 77023 = 77120
103 + 77017 = 77120
157 + 76963 = 77120
283 + 76837 = 77120
349 + 76771 = 77120

Showing the first eight; more decompositions exist.
