Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646658, here are decompositions:

179 + 8646479 = 8646658
257 + 8646401 = 8646658
269 + 8646389 = 8646658
281 + 8646377 = 8646658
359 + 8646299 = 8646658
389 + 8646269 = 8646658
401 + 8646257 = 8646658
431 + 8646227 = 8646658

Showing the first eight; more decompositions exist.
