Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629170, here are decompositions:

13 + 8629157 = 8629170
29 + 8629141 = 8629170
31 + 8629139 = 8629170
47 + 8629123 = 8629170
61 + 8629109 = 8629170
83 + 8629087 = 8629170
97 + 8629073 = 8629170
107 + 8629063 = 8629170

Showing the first eight; more decompositions exist.
