Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743724, here are decompositions:

7 + 8743717 = 8743724
13 + 8743711 = 8743724
43 + 8743681 = 8743724
103 + 8743621 = 8743724
127 + 8743597 = 8743724
163 + 8743561 = 8743724
193 + 8743531 = 8743724
211 + 8743513 = 8743724

Showing the first eight; more decompositions exist.
