Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51842, here are decompositions:

3 + 51839 = 51842
13 + 51829 = 51842
73 + 51769 = 51842
151 + 51691 = 51842
163 + 51679 = 51842
211 + 51631 = 51842
229 + 51613 = 51842
331 + 51511 = 51842

Showing the first eight; more decompositions exist.
