Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623380, here are decompositions:

23 + 8623357 = 8623380
41 + 8623339 = 8623380
61 + 8623319 = 8623380
89 + 8623291 = 8623380
127 + 8623253 = 8623380
131 + 8623249 = 8623380
167 + 8623213 = 8623380
239 + 8623141 = 8623380

Showing the first eight; more decompositions exist.
