Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22782, here are decompositions:

5 + 22777 = 22782
13 + 22769 = 22782
31 + 22751 = 22782
41 + 22741 = 22782
43 + 22739 = 22782
61 + 22721 = 22782
73 + 22709 = 22782
83 + 22699 = 22782

Showing the first eight; more decompositions exist.
