Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661954, here are decompositions:

11 + 8661943 = 8661954
13 + 8661941 = 8661954
53 + 8661901 = 8661954
71 + 8661883 = 8661954
73 + 8661881 = 8661954
83 + 8661871 = 8661954
113 + 8661841 = 8661954
211 + 8661743 = 8661954

Showing the first eight; more decompositions exist.
