Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689938, here are decompositions:

97 + 8689841 = 8689938
139 + 8689799 = 8689938
211 + 8689727 = 8689938
227 + 8689711 = 8689938
251 + 8689687 = 8689938
277 + 8689661 = 8689938
281 + 8689657 = 8689938
311 + 8689627 = 8689938

Showing the first eight; more decompositions exist.
