Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637188, here are decompositions:

37 + 8637151 = 8637188
97 + 8637091 = 8637188
127 + 8637061 = 8637188
181 + 8637007 = 8637188
199 + 8636989 = 8637188
229 + 8636959 = 8637188
271 + 8636917 = 8637188
277 + 8636911 = 8637188

Showing the first eight; more decompositions exist.
