Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17790, here are decompositions:

7 + 17783 = 17790
29 + 17761 = 17790
41 + 17749 = 17790
43 + 17747 = 17790
53 + 17737 = 17790
61 + 17729 = 17790
83 + 17707 = 17790
107 + 17683 = 17790

Showing the first eight; more decompositions exist.
