Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61938, here are decompositions:

5 + 61933 = 61938
11 + 61927 = 61938
29 + 61909 = 61938
59 + 61879 = 61938
67 + 61871 = 61938
101 + 61837 = 61938
157 + 61781 = 61938
181 + 61757 = 61938

Showing the first eight; more decompositions exist.
