Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618130, here are decompositions:

11 + 8618119 = 8618130
23 + 8618107 = 8618130
41 + 8618089 = 8618130
43 + 8618087 = 8618130
47 + 8618083 = 8618130
67 + 8618063 = 8618130
71 + 8618059 = 8618130
83 + 8618047 = 8618130

Showing the first eight; more decompositions exist.
