Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664220, here are decompositions:

113 + 8664107 = 8664220
167 + 8664053 = 8664220
197 + 8664023 = 8664220
233 + 8663987 = 8664220
251 + 8663969 = 8664220
359 + 8663861 = 8664220
401 + 8663819 = 8664220
443 + 8663777 = 8664220

Showing the first eight; more decompositions exist.
