Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677220, here are decompositions:

163 + 8677057 = 8677220
193 + 8677027 = 8677220
229 + 8676991 = 8677220
271 + 8676949 = 8677220
283 + 8676937 = 8677220
337 + 8676883 = 8677220
373 + 8676847 = 8677220
421 + 8676799 = 8677220

Showing the first eight; more decompositions exist.
