Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30898, here are decompositions:

5 + 30893 = 30898
17 + 30881 = 30898
29 + 30869 = 30898
47 + 30851 = 30898
59 + 30839 = 30898
89 + 30809 = 30898
191 + 30707 = 30898
227 + 30671 = 30898

Showing the first eight; more decompositions exist.
