Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20852, here are decompositions:

3 + 20849 = 20852
43 + 20809 = 20852
79 + 20773 = 20852
103 + 20749 = 20852
109 + 20743 = 20852
211 + 20641 = 20852
241 + 20611 = 20852
331 + 20521 = 20852

Showing the first eight; more decompositions exist.
