Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623384, here are decompositions:

131 + 8623253 = 8623384
137 + 8623247 = 8623384
191 + 8623193 = 8623384
281 + 8623103 = 8623384
311 + 8623073 = 8623384
317 + 8623067 = 8623384
347 + 8623037 = 8623384
353 + 8623031 = 8623384

Showing the first eight; more decompositions exist.
