Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637164, here are decompositions:

13 + 8637151 = 8637164
31 + 8637133 = 8637164
61 + 8637103 = 8637164
73 + 8637091 = 8637164
97 + 8637067 = 8637164
103 + 8637061 = 8637164
157 + 8637007 = 8637164
241 + 8636923 = 8637164

Showing the first eight; more decompositions exist.
