Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616280, here are decompositions:

59 + 8616221 = 8616280
83 + 8616197 = 8616280
107 + 8616173 = 8616280
131 + 8616149 = 8616280
149 + 8616131 = 8616280
191 + 8616089 = 8616280
251 + 8616029 = 8616280
269 + 8616011 = 8616280

Showing the first eight; more decompositions exist.
