Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27798, here are decompositions:

5 + 27793 = 27798
7 + 27791 = 27798
19 + 27779 = 27798
31 + 27767 = 27798
47 + 27751 = 27798
59 + 27739 = 27798
61 + 27737 = 27798
97 + 27701 = 27798

Showing the first eight; more decompositions exist.
