Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11850, here are decompositions:

11 + 11839 = 11850
17 + 11833 = 11850
19 + 11831 = 11850
23 + 11827 = 11850
29 + 11821 = 11850
37 + 11813 = 11850
43 + 11807 = 11850
61 + 11789 = 11850

Showing the first eight; more decompositions exist.
