Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77172, here are decompositions:

5 + 77167 = 77172
19 + 77153 = 77172
31 + 77141 = 77172
71 + 77101 = 77172
79 + 77093 = 77172
103 + 77069 = 77172
131 + 77041 = 77172
149 + 77023 = 77172

Showing the first eight; more decompositions exist.
