Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649194, here are decompositions:

3 + 8649191 = 8649194
7 + 8649187 = 8649194
193 + 8649001 = 8649194
241 + 8648953 = 8649194
271 + 8648923 = 8649194
313 + 8648881 = 8649194
331 + 8648863 = 8649194
397 + 8648797 = 8649194

Showing the first eight; more decompositions exist.
