Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689390, here are decompositions:

41 + 8689349 = 8689390
71 + 8689319 = 8689390
89 + 8689301 = 8689390
107 + 8689283 = 8689390
131 + 8689259 = 8689390
167 + 8689223 = 8689390
173 + 8689217 = 8689390
257 + 8689133 = 8689390

Showing the first eight; more decompositions exist.
