Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31170, here are decompositions:

11 + 31159 = 31170
17 + 31153 = 31170
19 + 31151 = 31170
23 + 31147 = 31170
31 + 31139 = 31170
47 + 31123 = 31170
79 + 31091 = 31170
89 + 31081 = 31170

Showing the first eight; more decompositions exist.
