Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71038, here are decompositions:

41 + 70997 = 71038
47 + 70991 = 71038
59 + 70979 = 71038
89 + 70949 = 71038
101 + 70937 = 71038
137 + 70901 = 71038
197 + 70841 = 71038
269 + 70769 = 71038

Showing the first eight; more decompositions exist.
