Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616842, here are decompositions:

61 + 8616781 = 8616842
79 + 8616763 = 8616842
109 + 8616733 = 8616842
139 + 8616703 = 8616842
151 + 8616691 = 8616842
163 + 8616679 = 8616842
181 + 8616661 = 8616842
349 + 8616493 = 8616842

Showing the first eight; more decompositions exist.
