Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67790, here are decompositions:

7 + 67783 = 67790
13 + 67777 = 67790
31 + 67759 = 67790
67 + 67723 = 67790
139 + 67651 = 67790
211 + 67579 = 67790
223 + 67567 = 67790
313 + 67477 = 67790

Showing the first eight; more decompositions exist.
