Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37824, here are decompositions:

11 + 37813 = 37824
13 + 37811 = 37824
41 + 37783 = 37824
43 + 37781 = 37824
107 + 37717 = 37824
131 + 37693 = 37824
167 + 37657 = 37824
181 + 37643 = 37824

Showing the first eight; more decompositions exist.
