Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757966, here are decompositions:

5 + 8757961 = 8757966
23 + 8757943 = 8757966
47 + 8757919 = 8757966
73 + 8757893 = 8757966
89 + 8757877 = 8757966
109 + 8757857 = 8757966
137 + 8757829 = 8757966
149 + 8757817 = 8757966

Showing the first eight; more decompositions exist.
