Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71036, here are decompositions:

13 + 71023 = 71036
37 + 70999 = 71036
67 + 70969 = 71036
79 + 70957 = 71036
157 + 70879 = 71036
193 + 70843 = 71036
283 + 70753 = 71036
307 + 70729 = 71036

Showing the first eight; more decompositions exist.
