Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649290, here are decompositions:

7 + 8649283 = 8649290
37 + 8649253 = 8649290
79 + 8649211 = 8649290
103 + 8649187 = 8649290
211 + 8649079 = 8649290
229 + 8649061 = 8649290
241 + 8649049 = 8649290
337 + 8648953 = 8649290

Showing the first eight; more decompositions exist.
