Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692990, here are decompositions:

3 + 8692987 = 8692990
17 + 8692973 = 8692990
29 + 8692961 = 8692990
83 + 8692907 = 8692990
101 + 8692889 = 8692990
113 + 8692877 = 8692990
149 + 8692841 = 8692990
191 + 8692799 = 8692990

Showing the first eight; more decompositions exist.
