Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10842, here are decompositions:

5 + 10837 = 10842
11 + 10831 = 10842
43 + 10799 = 10842
53 + 10789 = 10842
61 + 10781 = 10842
71 + 10771 = 10842
89 + 10753 = 10842
103 + 10739 = 10842

Showing the first eight; more decompositions exist.
