Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9170, here are decompositions:

13 + 9157 = 9170
19 + 9151 = 9170
37 + 9133 = 9170
43 + 9127 = 9170
61 + 9109 = 9170
67 + 9103 = 9170
79 + 9091 = 9170
103 + 9067 = 9170

Showing the first eight; more decompositions exist.
