Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618112, here are decompositions:

5 + 8618107 = 8618112
23 + 8618089 = 8618112
29 + 8618083 = 8618112
53 + 8618059 = 8618112
71 + 8618041 = 8618112
79 + 8618033 = 8618112
163 + 8617949 = 8618112
179 + 8617933 = 8618112

Showing the first eight; more decompositions exist.
