Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617028, here are decompositions:

31 + 8616997 = 8617028
37 + 8616991 = 8617028
109 + 8616919 = 8617028
127 + 8616901 = 8617028
271 + 8616757 = 8617028
307 + 8616721 = 8617028
337 + 8616691 = 8617028
349 + 8616679 = 8617028

Showing the first eight; more decompositions exist.
