Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618100, here are decompositions:

11 + 8618089 = 8618100
13 + 8618087 = 8618100
17 + 8618083 = 8618100
37 + 8618063 = 8618100
41 + 8618059 = 8618100
53 + 8618047 = 8618100
59 + 8618041 = 8618100
67 + 8618033 = 8618100

Showing the first eight; more decompositions exist.
