Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91974, here are decompositions:

5 + 91969 = 91974
7 + 91967 = 91974
13 + 91961 = 91974
17 + 91957 = 91974
23 + 91951 = 91974
31 + 91943 = 91974
53 + 91921 = 91974
101 + 91873 = 91974

Showing the first eight; more decompositions exist.
