Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642950, here are decompositions:

3 + 8642947 = 8642950
11 + 8642939 = 8642950
23 + 8642927 = 8642950
47 + 8642903 = 8642950
53 + 8642897 = 8642950
89 + 8642861 = 8642950
101 + 8642849 = 8642950
131 + 8642819 = 8642950

Showing the first eight; more decompositions exist.
