Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626842, here are decompositions:

11 + 8626831 = 8626842
19 + 8626823 = 8626842
23 + 8626819 = 8626842
31 + 8626811 = 8626842
41 + 8626801 = 8626842
79 + 8626763 = 8626842
109 + 8626733 = 8626842
151 + 8626691 = 8626842

Showing the first eight; more decompositions exist.
