Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623488, here are decompositions:

59 + 8623429 = 8623488
79 + 8623409 = 8623488
131 + 8623357 = 8623488
149 + 8623339 = 8623488
197 + 8623291 = 8623488
227 + 8623261 = 8623488
239 + 8623249 = 8623488
241 + 8623247 = 8623488

Showing the first eight; more decompositions exist.
