Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70780, here are decompositions:

11 + 70769 = 70780
71 + 70709 = 70780
113 + 70667 = 70780
173 + 70607 = 70780
191 + 70589 = 70780
197 + 70583 = 70780
251 + 70529 = 70780
293 + 70487 = 70780

Showing the first eight; more decompositions exist.
