Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77186, here are decompositions:

19 + 77167 = 77186
139 + 77047 = 77186
157 + 77029 = 77186
163 + 77023 = 77186
223 + 76963 = 77186
313 + 76873 = 77186
349 + 76837 = 77186
367 + 76819 = 77186

Showing the first eight; more decompositions exist.
