Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623392, here are decompositions:

53 + 8623339 = 8623392
73 + 8623319 = 8623392
101 + 8623291 = 8623392
131 + 8623261 = 8623392
139 + 8623253 = 8623392
179 + 8623213 = 8623392
199 + 8623193 = 8623392
251 + 8623141 = 8623392

Showing the first eight; more decompositions exist.
