Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679972, here are decompositions:

19 + 8679953 = 8679972
29 + 8679943 = 8679972
73 + 8679899 = 8679972
89 + 8679883 = 8679972
101 + 8679871 = 8679972
131 + 8679841 = 8679972
181 + 8679791 = 8679972
229 + 8679743 = 8679972

Showing the first eight; more decompositions exist.
