Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656478, here are decompositions:

67 + 8656411 = 8656478
79 + 8656399 = 8656478
109 + 8656369 = 8656478
139 + 8656339 = 8656478
157 + 8656321 = 8656478
199 + 8656279 = 8656478
307 + 8656171 = 8656478
331 + 8656147 = 8656478

Showing the first eight; more decompositions exist.
