Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621044, here are decompositions:

71 + 8620973 = 8621044
101 + 8620943 = 8621044
197 + 8620847 = 8621044
317 + 8620727 = 8621044
353 + 8620691 = 8621044
491 + 8620553 = 8621044
683 + 8620361 = 8621044
827 + 8620217 = 8621044

Showing the first eight; more decompositions exist.
