Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649458, here are decompositions:

7 + 8649451 = 8649458
67 + 8649391 = 8649458
109 + 8649349 = 8649458
127 + 8649331 = 8649458
271 + 8649187 = 8649458
379 + 8649079 = 8649458
397 + 8649061 = 8649458
409 + 8649049 = 8649458

Showing the first eight; more decompositions exist.
