Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626724, here are decompositions:

103 + 8626621 = 8626724
307 + 8626417 = 8626724
487 + 8626237 = 8626724
661 + 8626063 = 8626724
727 + 8625997 = 8626724
751 + 8625973 = 8626724
811 + 8625913 = 8626724
823 + 8625901 = 8626724

Showing the first eight; more decompositions exist.
