Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89842, here are decompositions:

3 + 89839 = 89842
23 + 89819 = 89842
59 + 89783 = 89842
83 + 89759 = 89842
89 + 89753 = 89842
173 + 89669 = 89842
239 + 89603 = 89842
251 + 89591 = 89842

Showing the first eight; more decompositions exist.
