Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662170, here are decompositions:

17 + 8662153 = 8662170
19 + 8662151 = 8662170
37 + 8662133 = 8662170
43 + 8662127 = 8662170
61 + 8662109 = 8662170
79 + 8662091 = 8662170
113 + 8662057 = 8662170
149 + 8662021 = 8662170

Showing the first eight; more decompositions exist.
