Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51836, here are decompositions:

7 + 51829 = 51836
19 + 51817 = 51836
67 + 51769 = 51836
157 + 51679 = 51836
163 + 51673 = 51836
199 + 51637 = 51836
223 + 51613 = 51836
229 + 51607 = 51836

Showing the first eight; more decompositions exist.
