Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47940, here are decompositions:

7 + 47933 = 47940
23 + 47917 = 47940
29 + 47911 = 47940
37 + 47903 = 47940
59 + 47881 = 47940
71 + 47869 = 47940
83 + 47857 = 47940
97 + 47843 = 47940

Showing the first eight; more decompositions exist.
