Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51824, here are decompositions:

7 + 51817 = 51824
37 + 51787 = 51824
103 + 51721 = 51824
151 + 51673 = 51824
193 + 51631 = 51824
211 + 51613 = 51824
307 + 51517 = 51824
313 + 51511 = 51824

Showing the first eight; more decompositions exist.
