Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743712, here are decompositions:

31 + 8743681 = 8743712
73 + 8743639 = 8743712
79 + 8743633 = 8743712
151 + 8743561 = 8743712
163 + 8743549 = 8743712
181 + 8743531 = 8743712
199 + 8743513 = 8743712
223 + 8743489 = 8743712

Showing the first eight; more decompositions exist.
