Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680018, here are decompositions:

47 + 8679971 = 8680018
131 + 8679887 = 8680018
227 + 8679791 = 8680018
251 + 8679767 = 8680018
401 + 8679617 = 8680018
461 + 8679557 = 8680018
467 + 8679551 = 8680018
491 + 8679527 = 8680018

Showing the first eight; more decompositions exist.
