Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689984, here are decompositions:

3 + 8689981 = 8689984
5 + 8689979 = 8689984
41 + 8689943 = 8689984
131 + 8689853 = 8689984
167 + 8689817 = 8689984
257 + 8689727 = 8689984
311 + 8689673 = 8689984
431 + 8689553 = 8689984

Showing the first eight; more decompositions exist.
