Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618108, here are decompositions:

19 + 8618089 = 8618108
61 + 8618047 = 8618108
67 + 8618041 = 8618108
181 + 8617927 = 8618108
271 + 8617837 = 8618108
409 + 8617699 = 8618108
547 + 8617561 = 8618108
661 + 8617447 = 8618108

Showing the first eight; more decompositions exist.
