Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680120, here are decompositions:

17 + 8680103 = 8680120
47 + 8680073 = 8680120
83 + 8680037 = 8680120
149 + 8679971 = 8680120
167 + 8679953 = 8680120
233 + 8679887 = 8680120
353 + 8679767 = 8680120
443 + 8679677 = 8680120

Showing the first eight; more decompositions exist.
