Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623416, here are decompositions:

7 + 8623409 = 8623416
23 + 8623393 = 8623416
59 + 8623357 = 8623416
97 + 8623319 = 8623416
163 + 8623253 = 8623416
167 + 8623249 = 8623416
223 + 8623193 = 8623416
293 + 8623123 = 8623416

Showing the first eight; more decompositions exist.
