Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575010, here are decompositions:

11 + 31574999 = 31575010
29 + 31574981 = 31575010
41 + 31574969 = 31575010
83 + 31574927 = 31575010
149 + 31574861 = 31575010
197 + 31574813 = 31575010
263 + 31574747 = 31575010
317 + 31574693 = 31575010

Showing the first eight; more decompositions exist.
