Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71938, here are decompositions:

5 + 71933 = 71938
29 + 71909 = 71938
59 + 71879 = 71938
71 + 71867 = 71938
89 + 71849 = 71938
101 + 71837 = 71938
131 + 71807 = 71938
149 + 71789 = 71938

Showing the first eight; more decompositions exist.
