Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759220, here are decompositions:

13 + 8759207 = 8759220
37 + 8759183 = 8759220
53 + 8759167 = 8759220
59 + 8759161 = 8759220
79 + 8759141 = 8759220
83 + 8759137 = 8759220
97 + 8759123 = 8759220
131 + 8759089 = 8759220

Showing the first eight; more decompositions exist.
