Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743616, here are decompositions:

19 + 8743597 = 8743616
67 + 8743549 = 8743616
103 + 8743513 = 8743616
127 + 8743489 = 8743616
157 + 8743459 = 8743616
163 + 8743453 = 8743616
199 + 8743417 = 8743616
223 + 8743393 = 8743616

Showing the first eight; more decompositions exist.
