Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38790, here are decompositions:

7 + 38783 = 38790
23 + 38767 = 38790
41 + 38749 = 38790
43 + 38747 = 38790
53 + 38737 = 38790
61 + 38729 = 38790
67 + 38723 = 38790
79 + 38711 = 38790

Showing the first eight; more decompositions exist.
