Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77190, here are decompositions:

19 + 77171 = 77190
23 + 77167 = 77190
37 + 77153 = 77190
53 + 77137 = 77190
89 + 77101 = 77190
97 + 77093 = 77190
109 + 77081 = 77190
149 + 77041 = 77190

Showing the first eight; more decompositions exist.
