Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987882, here are decompositions:

13 + 987869 = 987882
31 + 987851 = 987882
61 + 987821 = 987882
73 + 987809 = 987882
79 + 987803 = 987882
89 + 987793 = 987882
223 + 987659 = 987882
251 + 987631 = 987882

Showing the first eight; more decompositions exist.
