Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51872, here are decompositions:

3 + 51869 = 51872
13 + 51859 = 51872
19 + 51853 = 51872
43 + 51829 = 51872
103 + 51769 = 51872
151 + 51721 = 51872
181 + 51691 = 51872
193 + 51679 = 51872

Showing the first eight; more decompositions exist.
