Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628178, here are decompositions:

5 + 8628173 = 8628178
17 + 8628161 = 8628178
29 + 8628149 = 8628178
47 + 8628131 = 8628178
71 + 8628107 = 8628178
101 + 8628077 = 8628178
191 + 8627987 = 8628178
239 + 8627939 = 8628178

Showing the first eight; more decompositions exist.
