Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652220, here are decompositions:

167 + 8652053 = 8652220
173 + 8652047 = 8652220
179 + 8652041 = 8652220
191 + 8652029 = 8652220
197 + 8652023 = 8652220
281 + 8651939 = 8652220
449 + 8651771 = 8652220
503 + 8651717 = 8652220

Showing the first eight; more decompositions exist.
