Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37940, here are decompositions:

43 + 37897 = 37940
61 + 37879 = 37940
79 + 37861 = 37940
109 + 37831 = 37940
127 + 37813 = 37940
157 + 37783 = 37940
193 + 37747 = 37940
223 + 37717 = 37940

Showing the first eight; more decompositions exist.
