Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725328, here are decompositions:

109 + 8725219 = 8725328
151 + 8725177 = 8725328
181 + 8725147 = 8725328
229 + 8725099 = 8725328
277 + 8725051 = 8725328
307 + 8725021 = 8725328
379 + 8724949 = 8725328
457 + 8724871 = 8725328

Showing the first eight; more decompositions exist.
