Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482984, here are decompositions:

7 + 31482977 = 31482984
11 + 31482973 = 31482984
37 + 31482947 = 31482984
151 + 31482833 = 31482984
163 + 31482821 = 31482984
223 + 31482761 = 31482984
241 + 31482743 = 31482984
277 + 31482707 = 31482984

Showing the first eight; more decompositions exist.
