Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657724, here are decompositions:

37 + 8657687 = 8657724
43 + 8657681 = 8657724
73 + 8657651 = 8657724
113 + 8657611 = 8657724
157 + 8657567 = 8657724
167 + 8657557 = 8657724
191 + 8657533 = 8657724
211 + 8657513 = 8657724

Showing the first eight; more decompositions exist.
