Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723724, here are decompositions:

17 + 8723707 = 8723724
47 + 8723677 = 8723724
71 + 8723653 = 8723724
131 + 8723593 = 8723724
173 + 8723551 = 8723724
193 + 8723531 = 8723724
227 + 8723497 = 8723724
241 + 8723483 = 8723724

Showing the first eight; more decompositions exist.
