Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757220, here are decompositions:

11 + 8757209 = 8757220
29 + 8757191 = 8757220
41 + 8757179 = 8757220
47 + 8757173 = 8757220
89 + 8757131 = 8757220
107 + 8757113 = 8757220
113 + 8757107 = 8757220
137 + 8757083 = 8757220

Showing the first eight; more decompositions exist.
