Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623272, here are decompositions:

11 + 8623261 = 8623272
19 + 8623253 = 8623272
23 + 8623249 = 8623272
59 + 8623213 = 8623272
79 + 8623193 = 8623272
131 + 8623141 = 8623272
149 + 8623123 = 8623272
191 + 8623081 = 8623272

Showing the first eight; more decompositions exist.
