Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623388, here are decompositions:

31 + 8623357 = 8623388
97 + 8623291 = 8623388
127 + 8623261 = 8623388
139 + 8623249 = 8623388
307 + 8623081 = 8623388
337 + 8623051 = 8623388
349 + 8623039 = 8623388
541 + 8622847 = 8623388

Showing the first eight; more decompositions exist.
