Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631556, here are decompositions:

23 + 8631533 = 8631556
389 + 8631167 = 8631556
653 + 8630903 = 8631556
719 + 8630837 = 8631556
743 + 8630813 = 8631556
797 + 8630759 = 8631556
887 + 8630669 = 8631556
1307 + 8630249 = 8631556

Showing the first eight; more decompositions exist.
