Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98638, here are decompositions:

11 + 98627 = 98638
17 + 98621 = 98638
41 + 98597 = 98638
131 + 98507 = 98638
179 + 98459 = 98638
227 + 98411 = 98638
251 + 98387 = 98638
269 + 98369 = 98638

Showing the first eight; more decompositions exist.
