Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757980, here are decompositions:

19 + 8757961 = 8757980
37 + 8757943 = 8757980
61 + 8757919 = 8757980
103 + 8757877 = 8757980
151 + 8757829 = 8757980
163 + 8757817 = 8757980
181 + 8757799 = 8757980
211 + 8757769 = 8757980

Showing the first eight; more decompositions exist.
