Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70858, here are decompositions:

5 + 70853 = 70858
17 + 70841 = 70858
89 + 70769 = 70858
149 + 70709 = 70858
191 + 70667 = 70858
239 + 70619 = 70858
251 + 70607 = 70858
269 + 70589 = 70858

Showing the first eight; more decompositions exist.
