Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680216, here are decompositions:

3 + 8680213 = 8680216
29 + 8680187 = 8680216
59 + 8680157 = 8680216
113 + 8680103 = 8680216
173 + 8680043 = 8680216
179 + 8680037 = 8680216
263 + 8679953 = 8680216
317 + 8679899 = 8680216

Showing the first eight; more decompositions exist.
