Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681972, here are decompositions:

3 + 8681969 = 8681972
31 + 8681941 = 8681972
73 + 8681899 = 8681972
151 + 8681821 = 8681972
193 + 8681779 = 8681972
241 + 8681731 = 8681972
349 + 8681623 = 8681972
433 + 8681539 = 8681972

Showing the first eight; more decompositions exist.
