Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18798, here are decompositions:

5 + 18793 = 18798
11 + 18787 = 18798
41 + 18757 = 18798
67 + 18731 = 18798
79 + 18719 = 18798
97 + 18701 = 18798
107 + 18691 = 18798
127 + 18671 = 18798

Showing the first eight; more decompositions exist.
