Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131964, here are decompositions:

5 + 131959 = 131964
17 + 131947 = 131964
23 + 131941 = 131964
31 + 131933 = 131964
37 + 131927 = 131964
71 + 131893 = 131964
73 + 131891 = 131964
103 + 131861 = 131964

Showing the first eight; more decompositions exist.
