Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649204, here are decompositions:

7 + 8649197 = 8649204
13 + 8649191 = 8649204
17 + 8649187 = 8649204
101 + 8649103 = 8649204
181 + 8649023 = 8649204
251 + 8648953 = 8649204
281 + 8648923 = 8649204
283 + 8648921 = 8649204

Showing the first eight; more decompositions exist.
