Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131958, here are decompositions:

11 + 131947 = 131958
17 + 131941 = 131958
19 + 131939 = 131958
31 + 131927 = 131958
59 + 131899 = 131958
67 + 131891 = 131958
97 + 131861 = 131958
109 + 131849 = 131958

Showing the first eight; more decompositions exist.
