Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621116, here are decompositions:

29 + 8621087 = 8621116
107 + 8621009 = 8621116
167 + 8620949 = 8621116
173 + 8620943 = 8621116
269 + 8620847 = 8621116
359 + 8620757 = 8621116
389 + 8620727 = 8621116
443 + 8620673 = 8621116

Showing the first eight; more decompositions exist.
