Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11958, here are decompositions:

5 + 11953 = 11958
17 + 11941 = 11958
19 + 11939 = 11958
31 + 11927 = 11958
61 + 11897 = 11958
71 + 11887 = 11958
127 + 11831 = 11958
131 + 11827 = 11958

Showing the first eight; more decompositions exist.
