Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638008, here are decompositions:

17 + 8637991 = 8638008
79 + 8637929 = 8638008
139 + 8637869 = 8638008
179 + 8637829 = 8638008
229 + 8637779 = 8638008
307 + 8637701 = 8638008
311 + 8637697 = 8638008
367 + 8637641 = 8638008

Showing the first eight; more decompositions exist.
