Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634988, here are decompositions:

17 + 8634971 = 8634988
41 + 8634947 = 8634988
71 + 8634917 = 8634988
107 + 8634881 = 8634988
137 + 8634851 = 8634988
149 + 8634839 = 8634988
227 + 8634761 = 8634988
311 + 8634677 = 8634988

Showing the first eight; more decompositions exist.
