Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637158, here are decompositions:

7 + 8637151 = 8637158
67 + 8637091 = 8637158
97 + 8637061 = 8637158
151 + 8637007 = 8637158
199 + 8636959 = 8637158
241 + 8636917 = 8637158
367 + 8636791 = 8637158
379 + 8636779 = 8637158

Showing the first eight; more decompositions exist.
