Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513024, here are decompositions:

17 + 31513007 = 31513024
131 + 31512893 = 31513024
197 + 31512827 = 31513024
293 + 31512731 = 31513024
467 + 31512557 = 31513024
503 + 31512521 = 31513024
677 + 31512347 = 31513024
863 + 31512161 = 31513024

Showing the first eight; more decompositions exist.
