Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710420, here are decompositions:

23 + 8710397 = 8710420
83 + 8710337 = 8710420
107 + 8710313 = 8710420
149 + 8710271 = 8710420
167 + 8710253 = 8710420
179 + 8710241 = 8710420
227 + 8710193 = 8710420
293 + 8710127 = 8710420

Showing the first eight; more decompositions exist.
