Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623320, here are decompositions:

29 + 8623291 = 8623320
59 + 8623261 = 8623320
67 + 8623253 = 8623320
71 + 8623249 = 8623320
73 + 8623247 = 8623320
107 + 8623213 = 8623320
127 + 8623193 = 8623320
179 + 8623141 = 8623320

Showing the first eight; more decompositions exist.
