Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698990, here are decompositions:

17 + 8698973 = 8698990
29 + 8698961 = 8698990
59 + 8698931 = 8698990
101 + 8698889 = 8698990
149 + 8698841 = 8698990
227 + 8698763 = 8698990
233 + 8698757 = 8698990
263 + 8698727 = 8698990

Showing the first eight; more decompositions exist.
