Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661058, here are decompositions:

11 + 8661047 = 8661058
71 + 8660987 = 8661058
89 + 8660969 = 8661058
137 + 8660921 = 8661058
149 + 8660909 = 8661058
167 + 8660891 = 8661058
239 + 8660819 = 8661058
311 + 8660747 = 8661058

Showing the first eight; more decompositions exist.
