Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77170, here are decompositions:

3 + 77167 = 77170
17 + 77153 = 77170
29 + 77141 = 77170
89 + 77081 = 77170
101 + 77069 = 77170
167 + 77003 = 77170
179 + 76991 = 77170
227 + 76943 = 77170

Showing the first eight; more decompositions exist.
