Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483000, here are decompositions:

23 + 31482977 = 31483000
53 + 31482947 = 31483000
167 + 31482833 = 31483000
179 + 31482821 = 31483000
239 + 31482761 = 31483000
257 + 31482743 = 31483000
293 + 31482707 = 31483000
317 + 31482683 = 31483000

Showing the first eight; more decompositions exist.
