Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637108, here are decompositions:

5 + 8637103 = 8637108
17 + 8637091 = 8637108
41 + 8637067 = 8637108
47 + 8637061 = 8637108
101 + 8637007 = 8637108
149 + 8636959 = 8637108
191 + 8636917 = 8637108
197 + 8636911 = 8637108

Showing the first eight; more decompositions exist.
