Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77182, here are decompositions:

11 + 77171 = 77182
29 + 77153 = 77182
41 + 77141 = 77182
89 + 77093 = 77182
101 + 77081 = 77182
113 + 77069 = 77182
179 + 77003 = 77182
191 + 76991 = 77182

Showing the first eight; more decompositions exist.
