Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694490, here are decompositions:

11 + 8694479 = 8694490
41 + 8694449 = 8694490
149 + 8694341 = 8694490
173 + 8694317 = 8694490
251 + 8694239 = 8694490
257 + 8694233 = 8694490
269 + 8694221 = 8694490
293 + 8694197 = 8694490

Showing the first eight; more decompositions exist.
