Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42938, here are decompositions:

37 + 42901 = 42938
79 + 42859 = 42938
97 + 42841 = 42938
109 + 42829 = 42938
151 + 42787 = 42938
211 + 42727 = 42938
229 + 42709 = 42938
241 + 42697 = 42938

Showing the first eight; more decompositions exist.
