Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9862, here are decompositions:

3 + 9859 = 9862
5 + 9857 = 9862
11 + 9851 = 9862
23 + 9839 = 9862
29 + 9833 = 9862
59 + 9803 = 9862
71 + 9791 = 9862
113 + 9749 = 9862

Showing the first eight; more decompositions exist.
