Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77158, here are decompositions:

5 + 77153 = 77158
17 + 77141 = 77158
89 + 77069 = 77158
167 + 76991 = 77158
197 + 76961 = 77158
239 + 76919 = 77158
251 + 76907 = 77158
311 + 76847 = 77158

Showing the first eight; more decompositions exist.
