Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31836, here are decompositions:

19 + 31817 = 31836
37 + 31799 = 31836
43 + 31793 = 31836
67 + 31769 = 31836
107 + 31729 = 31836
109 + 31727 = 31836
113 + 31723 = 31836
137 + 31699 = 31836

Showing the first eight; more decompositions exist.
