Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661956, here are decompositions:

3 + 8661953 = 8661956
13 + 8661943 = 8661956
67 + 8661889 = 8661956
73 + 8661883 = 8661956
157 + 8661799 = 8661956
223 + 8661733 = 8661956
229 + 8661727 = 8661956
283 + 8661673 = 8661956

Showing the first eight; more decompositions exist.
