Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627178, here are decompositions:

5 + 8627173 = 8627178
11 + 8627167 = 8627178
17 + 8627161 = 8627178
29 + 8627149 = 8627178
31 + 8627147 = 8627178
37 + 8627141 = 8627178
59 + 8627119 = 8627178
67 + 8627111 = 8627178

Showing the first eight; more decompositions exist.
