Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745664, here are decompositions:

107 + 8745557 = 8745664
113 + 8745551 = 8745664
227 + 8745437 = 8745664
311 + 8745353 = 8745664
353 + 8745311 = 8745664
461 + 8745203 = 8745664
503 + 8745161 = 8745664
563 + 8745101 = 8745664

Showing the first eight; more decompositions exist.
