Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575024, here are decompositions:

43 + 31574981 = 31575024
97 + 31574927 = 31575024
113 + 31574911 = 31575024
137 + 31574887 = 31575024
163 + 31574861 = 31575024
211 + 31574813 = 31575024
251 + 31574773 = 31575024
277 + 31574747 = 31575024

Showing the first eight; more decompositions exist.
