Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621160, here are decompositions:

7 + 8621153 = 8621160
13 + 8621147 = 8621160
17 + 8621143 = 8621160
59 + 8621101 = 8621160
71 + 8621089 = 8621160
73 + 8621087 = 8621160
83 + 8621077 = 8621160
109 + 8621051 = 8621160

Showing the first eight; more decompositions exist.
