Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31070, here are decompositions:

7 + 31063 = 31070
19 + 31051 = 31070
31 + 31039 = 31070
37 + 31033 = 31070
139 + 30931 = 31070
199 + 30871 = 31070
211 + 30859 = 31070
229 + 30841 = 31070

Showing the first eight; more decompositions exist.
