Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743664, here are decompositions:

31 + 8743633 = 8743664
43 + 8743621 = 8743664
67 + 8743597 = 8743664
103 + 8743561 = 8743664
151 + 8743513 = 8743664
211 + 8743453 = 8743664
271 + 8743393 = 8743664
337 + 8743327 = 8743664

Showing the first eight; more decompositions exist.
