Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646940, here are decompositions:

11 + 8646929 = 8646940
41 + 8646899 = 8646940
89 + 8646851 = 8646940
233 + 8646707 = 8646940
257 + 8646683 = 8646940
359 + 8646581 = 8646940
443 + 8646497 = 8646940
461 + 8646479 = 8646940

Showing the first eight; more decompositions exist.
