Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623472, here are decompositions:

43 + 8623429 = 8623472
79 + 8623393 = 8623472
181 + 8623291 = 8623472
211 + 8623261 = 8623472
223 + 8623249 = 8623472
331 + 8623141 = 8623472
349 + 8623123 = 8623472
421 + 8623051 = 8623472

Showing the first eight; more decompositions exist.
