Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623426, here are decompositions:

3 + 8623423 = 8623426
17 + 8623409 = 8623426
107 + 8623319 = 8623426
173 + 8623253 = 8623426
179 + 8623247 = 8623426
233 + 8623193 = 8623426
353 + 8623073 = 8623426
359 + 8623067 = 8623426

Showing the first eight; more decompositions exist.
