Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70784, here are decompositions:

31 + 70753 = 70784
67 + 70717 = 70784
97 + 70687 = 70784
127 + 70657 = 70784
157 + 70627 = 70784
163 + 70621 = 70784
211 + 70573 = 70784
277 + 70507 = 70784

Showing the first eight; more decompositions exist.
