Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81070, here are decompositions:

23 + 81047 = 81070
29 + 81041 = 81070
47 + 81023 = 81070
53 + 81017 = 81070
107 + 80963 = 81070
137 + 80933 = 81070
173 + 80897 = 81070
239 + 80831 = 81070

Showing the first eight; more decompositions exist.
