Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623170, here are decompositions:

29 + 8623141 = 8623170
47 + 8623123 = 8623170
67 + 8623103 = 8623170
89 + 8623081 = 8623170
97 + 8623073 = 8623170
103 + 8623067 = 8623170
109 + 8623061 = 8623170
131 + 8623039 = 8623170

Showing the first eight; more decompositions exist.
