Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616738, here are decompositions:

5 + 8616733 = 8616738
17 + 8616721 = 8616738
19 + 8616719 = 8616738
47 + 8616691 = 8616738
59 + 8616679 = 8616738
139 + 8616599 = 8616738
191 + 8616547 = 8616738
197 + 8616541 = 8616738

Showing the first eight; more decompositions exist.
