Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757900, here are decompositions:

7 + 8757893 = 8757900
23 + 8757877 = 8757900
43 + 8757857 = 8757900
71 + 8757829 = 8757900
79 + 8757821 = 8757900
83 + 8757817 = 8757900
101 + 8757799 = 8757900
131 + 8757769 = 8757900

Showing the first eight; more decompositions exist.
