Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623446, here are decompositions:

17 + 8623429 = 8623446
23 + 8623423 = 8623446
37 + 8623409 = 8623446
53 + 8623393 = 8623446
89 + 8623357 = 8623446
107 + 8623339 = 8623446
127 + 8623319 = 8623446
193 + 8623253 = 8623446

Showing the first eight; more decompositions exist.
