Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47938, here are decompositions:

5 + 47933 = 47938
101 + 47837 = 47938
131 + 47807 = 47938
197 + 47741 = 47938
227 + 47711 = 47938
239 + 47699 = 47938
257 + 47681 = 47938
281 + 47657 = 47938

Showing the first eight; more decompositions exist.
