Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570946, here are decompositions:

7 + 31570939 = 31570946
37 + 31570909 = 31570946
73 + 31570873 = 31570946
79 + 31570867 = 31570946
103 + 31570843 = 31570946
439 + 31570507 = 31570946
487 + 31570459 = 31570946
499 + 31570447 = 31570946

Showing the first eight; more decompositions exist.
