Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697990, here are decompositions:

13 + 8697977 = 8697990
17 + 8697973 = 8697990
19 + 8697971 = 8697990
23 + 8697967 = 8697990
43 + 8697947 = 8697990
47 + 8697943 = 8697990
53 + 8697937 = 8697990
71 + 8697919 = 8697990

Showing the first eight; more decompositions exist.
