Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690020, here are decompositions:

23 + 8689997 = 8690020
41 + 8689979 = 8690020
71 + 8689949 = 8690020
167 + 8689853 = 8690020
179 + 8689841 = 8690020
197 + 8689823 = 8690020
293 + 8689727 = 8690020
347 + 8689673 = 8690020

Showing the first eight; more decompositions exist.
