Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623636, here are decompositions:

17 + 8623619 = 8623636
53 + 8623583 = 8623636
89 + 8623547 = 8623636
107 + 8623529 = 8623636
113 + 8623523 = 8623636
227 + 8623409 = 8623636
317 + 8623319 = 8623636
383 + 8623253 = 8623636

Showing the first eight; more decompositions exist.
