Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127938, here are decompositions:

7 + 127931 = 127938
17 + 127921 = 127938
61 + 127877 = 127938
71 + 127867 = 127938
79 + 127859 = 127938
89 + 127849 = 127938
101 + 127837 = 127938
131 + 127807 = 127938

Showing the first eight; more decompositions exist.
