Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646688, here are decompositions:

5 + 8646683 = 8646688
107 + 8646581 = 8646688
191 + 8646497 = 8646688
311 + 8646377 = 8646688
359 + 8646329 = 8646688
389 + 8646299 = 8646688
419 + 8646269 = 8646688
431 + 8646257 = 8646688

Showing the first eight; more decompositions exist.
