Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680138, here are decompositions:

17 + 8680121 = 8680138
101 + 8680037 = 8680138
167 + 8679971 = 8680138
239 + 8679899 = 8680138
251 + 8679887 = 8680138
347 + 8679791 = 8680138
461 + 8679677 = 8680138
521 + 8679617 = 8680138

Showing the first eight; more decompositions exist.
