Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642946, here are decompositions:

7 + 8642939 = 8642946
19 + 8642927 = 8642946
43 + 8642903 = 8642946
83 + 8642863 = 8642946
89 + 8642857 = 8642946
97 + 8642849 = 8642946
107 + 8642839 = 8642946
127 + 8642819 = 8642946

Showing the first eight; more decompositions exist.
