Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697980, here are decompositions:

3 + 8697977 = 8697980
7 + 8697973 = 8697980
13 + 8697967 = 8697980
37 + 8697943 = 8697980
43 + 8697937 = 8697980
61 + 8697919 = 8697980
79 + 8697901 = 8697980
157 + 8697823 = 8697980

Showing the first eight; more decompositions exist.
