Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482964, here are decompositions:

17 + 31482947 = 31482964
131 + 31482833 = 31482964
257 + 31482707 = 31482964
281 + 31482683 = 31482964
347 + 31482617 = 31482964
563 + 31482401 = 31482964
683 + 31482281 = 31482964
797 + 31482167 = 31482964

Showing the first eight; more decompositions exist.
