Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681248, here are decompositions:

5 + 8681243 = 8681248
41 + 8681207 = 8681248
71 + 8681177 = 8681248
89 + 8681159 = 8681248
131 + 8681117 = 8681248
137 + 8681111 = 8681248
227 + 8681021 = 8681248
239 + 8681009 = 8681248

Showing the first eight; more decompositions exist.
