Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 957990, here are decompositions:

13 + 957977 = 957990
31 + 957959 = 957990
37 + 957953 = 957990
41 + 957949 = 957990
53 + 957937 = 957990
73 + 957917 = 957990
101 + 957889 = 957990
113 + 957877 = 957990

Showing the first eight; more decompositions exist.
