Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7170, here are decompositions:

11 + 7159 = 7170
19 + 7151 = 7170
41 + 7129 = 7170
43 + 7127 = 7170
61 + 7109 = 7170
67 + 7103 = 7170
101 + 7069 = 7170
113 + 7057 = 7170

Showing the first eight; more decompositions exist.
