Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70782, here are decompositions:

13 + 70769 = 70782
29 + 70753 = 70782
53 + 70729 = 70782
73 + 70709 = 70782
163 + 70619 = 70782
193 + 70589 = 70782
199 + 70583 = 70782
211 + 70571 = 70782

Showing the first eight; more decompositions exist.
