Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742344, here are decompositions:

31 + 8742313 = 8742344
151 + 8742193 = 8742344
157 + 8742187 = 8742344
211 + 8742133 = 8742344
223 + 8742121 = 8742344
241 + 8742103 = 8742344
277 + 8742067 = 8742344
307 + 8742037 = 8742344

Showing the first eight; more decompositions exist.
