Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68790, here are decompositions:

13 + 68777 = 68790
19 + 68771 = 68790
23 + 68767 = 68790
41 + 68749 = 68790
47 + 68743 = 68790
53 + 68737 = 68790
61 + 68729 = 68790
79 + 68711 = 68790

Showing the first eight; more decompositions exist.
