Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71006, here are decompositions:

7 + 70999 = 71006
37 + 70969 = 71006
127 + 70879 = 71006
139 + 70867 = 71006
157 + 70849 = 71006
163 + 70843 = 71006
223 + 70783 = 71006
277 + 70729 = 71006

Showing the first eight; more decompositions exist.
