Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70688, here are decompositions:

31 + 70657 = 70688
61 + 70627 = 70688
67 + 70621 = 70688
139 + 70549 = 70688
151 + 70537 = 70688
181 + 70507 = 70688
199 + 70489 = 70688
229 + 70459 = 70688

Showing the first eight; more decompositions exist.
