Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629724, here are decompositions:

13 + 8629711 = 8629724
43 + 8629681 = 8629724
73 + 8629651 = 8629724
127 + 8629597 = 8629724
163 + 8629561 = 8629724
241 + 8629483 = 8629724
277 + 8629447 = 8629724
283 + 8629441 = 8629724

Showing the first eight; more decompositions exist.
