Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71020, here are decompositions:

23 + 70997 = 71020
29 + 70991 = 71020
41 + 70979 = 71020
71 + 70949 = 71020
83 + 70937 = 71020
101 + 70919 = 71020
107 + 70913 = 71020
167 + 70853 = 71020

Showing the first eight; more decompositions exist.
