Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636678, here are decompositions:

7 + 8636671 = 8636678
31 + 8636647 = 8636678
79 + 8636599 = 8636678
97 + 8636581 = 8636678
139 + 8636539 = 8636678
157 + 8636521 = 8636678
229 + 8636449 = 8636678
331 + 8636347 = 8636678

Showing the first eight; more decompositions exist.
