Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680222, here are decompositions:

3 + 8680219 = 8680222
101 + 8680121 = 8680222
149 + 8680073 = 8680222
179 + 8680043 = 8680222
251 + 8679971 = 8680222
269 + 8679953 = 8680222
431 + 8679791 = 8680222
479 + 8679743 = 8680222

Showing the first eight; more decompositions exist.
