Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728950, here are decompositions:

7 + 8728943 = 8728950
23 + 8728927 = 8728950
29 + 8728921 = 8728950
47 + 8728903 = 8728950
53 + 8728897 = 8728950
67 + 8728883 = 8728950
101 + 8728849 = 8728950
127 + 8728823 = 8728950

Showing the first eight; more decompositions exist.
