Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710220, here are decompositions:

7 + 8710213 = 8710220
73 + 8710147 = 8710220
163 + 8710057 = 8710220
199 + 8710021 = 8710220
229 + 8709991 = 8710220
241 + 8709979 = 8710220
307 + 8709913 = 8710220
349 + 8709871 = 8710220

Showing the first eight; more decompositions exist.
