Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634678, here are decompositions:

7 + 8634671 = 8634678
11 + 8634667 = 8634678
61 + 8634617 = 8634678
97 + 8634581 = 8634678
127 + 8634551 = 8634678
139 + 8634539 = 8634678
181 + 8634497 = 8634678
197 + 8634481 = 8634678

Showing the first eight; more decompositions exist.
