Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661360, here are decompositions:

7 + 8661353 = 8661360
79 + 8661281 = 8661360
107 + 8661253 = 8661360
109 + 8661251 = 8661360
137 + 8661223 = 8661360
157 + 8661203 = 8661360
163 + 8661197 = 8661360
167 + 8661193 = 8661360

Showing the first eight; more decompositions exist.
