Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650678, here are decompositions:

5 + 8650673 = 8650678
11 + 8650667 = 8650678
137 + 8650541 = 8650678
167 + 8650511 = 8650678
191 + 8650487 = 8650678
227 + 8650451 = 8650678
269 + 8650409 = 8650678
317 + 8650361 = 8650678

Showing the first eight; more decompositions exist.
