Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657328, here are decompositions:

5 + 8657323 = 8657328
19 + 8657309 = 8657328
37 + 8657291 = 8657328
79 + 8657249 = 8657328
89 + 8657239 = 8657328
107 + 8657221 = 8657328
167 + 8657161 = 8657328
307 + 8657021 = 8657328

Showing the first eight; more decompositions exist.
