Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680078, here are decompositions:

5 + 8680073 = 8680078
41 + 8680037 = 8680078
107 + 8679971 = 8680078
179 + 8679899 = 8680078
191 + 8679887 = 8680078
311 + 8679767 = 8680078
401 + 8679677 = 8680078
461 + 8679617 = 8680078

Showing the first eight; more decompositions exist.
