Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618070, here are decompositions:

7 + 8618063 = 8618070
11 + 8618059 = 8618070
23 + 8618047 = 8618070
29 + 8618041 = 8618070
37 + 8618033 = 8618070
79 + 8617991 = 8618070
127 + 8617943 = 8618070
137 + 8617933 = 8618070

Showing the first eight; more decompositions exist.
