Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623422, here are decompositions:

13 + 8623409 = 8623422
29 + 8623393 = 8623422
83 + 8623339 = 8623422
103 + 8623319 = 8623422
131 + 8623291 = 8623422
173 + 8623249 = 8623422
229 + 8623193 = 8623422
281 + 8623141 = 8623422

Showing the first eight; more decompositions exist.
