Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697940, here are decompositions:

3 + 8697937 = 8697940
71 + 8697869 = 8697940
89 + 8697851 = 8697940
107 + 8697833 = 8697940
131 + 8697809 = 8697940
137 + 8697803 = 8697940
149 + 8697791 = 8697940
233 + 8697707 = 8697940

Showing the first eight; more decompositions exist.
