Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697178, here are decompositions:

71 + 8697107 = 8697178
89 + 8697089 = 8697178
179 + 8696999 = 8697178
227 + 8696951 = 8697178
239 + 8696939 = 8697178
311 + 8696867 = 8697178
389 + 8696789 = 8697178
419 + 8696759 = 8697178

Showing the first eight; more decompositions exist.
