Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699940, here are decompositions:

17 + 8699923 = 8699940
23 + 8699917 = 8699940
47 + 8699893 = 8699940
61 + 8699879 = 8699940
83 + 8699857 = 8699940
89 + 8699851 = 8699940
113 + 8699827 = 8699940
127 + 8699813 = 8699940

Showing the first eight; more decompositions exist.
