Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531024, here are decompositions:

23 + 31531001 = 31531024
47 + 31530977 = 31531024
131 + 31530893 = 31531024
191 + 31530833 = 31531024
197 + 31530827 = 31531024
227 + 31530797 = 31531024
251 + 31530773 = 31531024
311 + 31530713 = 31531024

Showing the first eight; more decompositions exist.
