Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27898, here are decompositions:

5 + 27893 = 27898
47 + 27851 = 27898
71 + 27827 = 27898
89 + 27809 = 27898
107 + 27791 = 27898
131 + 27767 = 27898
149 + 27749 = 27898
197 + 27701 = 27898

Showing the first eight; more decompositions exist.
