Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661944, here are decompositions:

3 + 8661941 = 8661944
43 + 8661901 = 8661944
61 + 8661883 = 8661944
73 + 8661871 = 8661944
103 + 8661841 = 8661944
211 + 8661733 = 8661944
241 + 8661703 = 8661944
271 + 8661673 = 8661944

Showing the first eight; more decompositions exist.
