Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28898, here are decompositions:

19 + 28879 = 28898
31 + 28867 = 28898
61 + 28837 = 28898
109 + 28789 = 28898
127 + 28771 = 28898
139 + 28759 = 28898
211 + 28687 = 28898
229 + 28669 = 28898

Showing the first eight; more decompositions exist.
