Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77194, here are decompositions:

3 + 77191 = 77194
23 + 77171 = 77194
41 + 77153 = 77194
53 + 77141 = 77194
101 + 77093 = 77194
113 + 77081 = 77194
191 + 77003 = 77194
233 + 76961 = 77194

Showing the first eight; more decompositions exist.
