Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27822, here are decompositions:

5 + 27817 = 27822
13 + 27809 = 27822
19 + 27803 = 27822
23 + 27799 = 27822
29 + 27793 = 27822
31 + 27791 = 27822
43 + 27779 = 27822
59 + 27763 = 27822

Showing the first eight; more decompositions exist.
