Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9842, here are decompositions:

3 + 9839 = 9842
13 + 9829 = 9842
31 + 9811 = 9842
61 + 9781 = 9842
73 + 9769 = 9842
103 + 9739 = 9842
109 + 9733 = 9842
163 + 9679 = 9842

Showing the first eight; more decompositions exist.
