Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637008, here are decompositions:

19 + 8636989 = 8637008
97 + 8636911 = 8637008
109 + 8636899 = 8637008
139 + 8636869 = 8637008
151 + 8636857 = 8637008
229 + 8636779 = 8637008
271 + 8636737 = 8637008
307 + 8636701 = 8637008

Showing the first eight; more decompositions exist.
