Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757828, here are decompositions:

7 + 8757821 = 8757828
11 + 8757817 = 8757828
19 + 8757809 = 8757828
29 + 8757799 = 8757828
59 + 8757769 = 8757828
71 + 8757757 = 8757828
109 + 8757719 = 8757828
127 + 8757701 = 8757828

Showing the first eight; more decompositions exist.
