Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663178, here are decompositions:

59 + 8663119 = 8663178
61 + 8663117 = 8663178
79 + 8663099 = 8663178
89 + 8663089 = 8663178
107 + 8663071 = 8663178
191 + 8662987 = 8663178
239 + 8662939 = 8663178
311 + 8662867 = 8663178

Showing the first eight; more decompositions exist.
