Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91938, here are decompositions:

17 + 91921 = 91938
29 + 91909 = 91938
71 + 91867 = 91938
97 + 91841 = 91938
101 + 91837 = 91938
127 + 91811 = 91938
131 + 91807 = 91938
137 + 91801 = 91938

Showing the first eight; more decompositions exist.
