Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653724, here are decompositions:

7 + 8653717 = 8653724
67 + 8653657 = 8653724
73 + 8653651 = 8653724
97 + 8653627 = 8653724
271 + 8653453 = 8653724
397 + 8653327 = 8653724
463 + 8653261 = 8653724
487 + 8653237 = 8653724

Showing the first eight; more decompositions exist.
