Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745636, here are decompositions:

23 + 8745613 = 8745636
79 + 8745557 = 8745636
83 + 8745553 = 8745636
89 + 8745547 = 8745636
113 + 8745523 = 8745636
199 + 8745437 = 8745636
269 + 8745367 = 8745636
283 + 8745353 = 8745636

Showing the first eight; more decompositions exist.
