Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4942, here are decompositions:

5 + 4937 = 4942
11 + 4931 = 4942
23 + 4919 = 4942
53 + 4889 = 4942
71 + 4871 = 4942
149 + 4793 = 4942
191 + 4751 = 4942
239 + 4703 = 4942

Showing the first eight; more decompositions exist.
