Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722368, here are decompositions:

7 + 8722361 = 8722368
29 + 8722339 = 8722368
37 + 8722331 = 8722368
71 + 8722297 = 8722368
131 + 8722237 = 8722368
157 + 8722211 = 8722368
181 + 8722187 = 8722368
197 + 8722171 = 8722368

Showing the first eight; more decompositions exist.
