Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661358, here are decompositions:

5 + 8661353 = 8661358
47 + 8661311 = 8661358
107 + 8661251 = 8661358
197 + 8661161 = 8661358
239 + 8661119 = 8661358
269 + 8661089 = 8661358
311 + 8661047 = 8661358
389 + 8660969 = 8661358

Showing the first eight; more decompositions exist.
