Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747966, here are decompositions:

37 + 8747929 = 8747966
103 + 8747863 = 8747966
109 + 8747857 = 8747966
163 + 8747803 = 8747966
223 + 8747743 = 8747966
229 + 8747737 = 8747966
277 + 8747689 = 8747966
313 + 8747653 = 8747966

Showing the first eight; more decompositions exist.
