Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483008, here are decompositions:

5 + 31483003 = 31483008
17 + 31482991 = 31483008
31 + 31482977 = 31483008
61 + 31482947 = 31483008
101 + 31482907 = 31483008
149 + 31482859 = 31483008
229 + 31482779 = 31483008
367 + 31482641 = 31483008

Showing the first eight; more decompositions exist.
