Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699864, here are decompositions:

7 + 8699857 = 8699864
13 + 8699851 = 8699864
37 + 8699827 = 8699864
223 + 8699641 = 8699864
307 + 8699557 = 8699864
331 + 8699533 = 8699864
421 + 8699443 = 8699864
571 + 8699293 = 8699864

Showing the first eight; more decompositions exist.
