Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482960, here are decompositions:

13 + 31482947 = 31482960
53 + 31482907 = 31482960
71 + 31482889 = 31482960
101 + 31482859 = 31482960
127 + 31482833 = 31482960
137 + 31482823 = 31482960
139 + 31482821 = 31482960
181 + 31482779 = 31482960

Showing the first eight; more decompositions exist.
