Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700220, here are decompositions:

59 + 8700161 = 8700220
107 + 8700113 = 8700220
149 + 8700071 = 8700220
173 + 8700047 = 8700220
227 + 8699993 = 8700220
239 + 8699981 = 8700220
251 + 8699969 = 8700220
449 + 8699771 = 8700220

Showing the first eight; more decompositions exist.
