Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103898, here are decompositions:

31 + 103867 = 103898
61 + 103837 = 103898
97 + 103801 = 103898
199 + 103699 = 103898
211 + 103687 = 103898
229 + 103669 = 103898
241 + 103657 = 103898
307 + 103591 = 103898

Showing the first eight; more decompositions exist.
