Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661118, here are decompositions:

29 + 8661089 = 8661118
71 + 8661047 = 8661118
131 + 8660987 = 8661118
149 + 8660969 = 8661118
197 + 8660921 = 8661118
227 + 8660891 = 8661118
419 + 8660699 = 8661118
461 + 8660657 = 8661118

Showing the first eight; more decompositions exist.
