Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649332, here are decompositions:

79 + 8649253 = 8649332
229 + 8649103 = 8649332
271 + 8649061 = 8649332
283 + 8649049 = 8649332
331 + 8649001 = 8649332
379 + 8648953 = 8649332
409 + 8648923 = 8649332
499 + 8648833 = 8649332

Showing the first eight; more decompositions exist.
