Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131994, here are decompositions:

47 + 131947 = 131994
53 + 131941 = 131994
61 + 131933 = 131994
67 + 131927 = 131994
101 + 131893 = 131994
103 + 131891 = 131994
157 + 131837 = 131994
197 + 131797 = 131994

Showing the first eight; more decompositions exist.
