Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20098, here are decompositions:

47 + 20051 = 20098
101 + 19997 = 20098
107 + 19991 = 20098
137 + 19961 = 20098
149 + 19949 = 20098
179 + 19919 = 20098
257 + 19841 = 20098
347 + 19751 = 20098

Showing the first eight; more decompositions exist.
