Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623420, here are decompositions:

11 + 8623409 = 8623420
101 + 8623319 = 8623420
167 + 8623253 = 8623420
173 + 8623247 = 8623420
227 + 8623193 = 8623420
317 + 8623103 = 8623420
347 + 8623073 = 8623420
353 + 8623067 = 8623420

Showing the first eight; more decompositions exist.
