Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18852, here are decompositions:

13 + 18839 = 18852
59 + 18793 = 18852
79 + 18773 = 18852
103 + 18749 = 18852
109 + 18743 = 18852
139 + 18713 = 18852
151 + 18701 = 18852
173 + 18679 = 18852

Showing the first eight; more decompositions exist.
