Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987834, here are decompositions:

13 + 987821 = 987834
31 + 987803 = 987834
37 + 987797 = 987834
41 + 987793 = 987834
137 + 987697 = 987834
227 + 987607 = 987834
241 + 987593 = 987834
293 + 987541 = 987834

Showing the first eight; more decompositions exist.
