Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680220, here are decompositions:

7 + 8680213 = 8680220
19 + 8680201 = 8680220
67 + 8680153 = 8680220
193 + 8680027 = 8680220
229 + 8679991 = 8680220
277 + 8679943 = 8680220
337 + 8679883 = 8680220
349 + 8679871 = 8680220

Showing the first eight; more decompositions exist.
