Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699966, here are decompositions:

7 + 8699959 = 8699966
13 + 8699953 = 8699966
19 + 8699947 = 8699966
43 + 8699923 = 8699966
73 + 8699893 = 8699966
109 + 8699857 = 8699966
139 + 8699827 = 8699966
307 + 8699659 = 8699966

Showing the first eight; more decompositions exist.
