Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621946, here are decompositions:

7 + 8621939 = 8621946
13 + 8621933 = 8621946
19 + 8621927 = 8621946
79 + 8621867 = 8621946
83 + 8621863 = 8621946
89 + 8621857 = 8621946
103 + 8621843 = 8621946
127 + 8621819 = 8621946

Showing the first eight; more decompositions exist.
