Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575060, here are decompositions:

19 + 31575041 = 31575060
61 + 31574999 = 31575060
71 + 31574989 = 31575060
79 + 31574981 = 31575060
149 + 31574911 = 31575060
173 + 31574887 = 31575060
197 + 31574863 = 31575060
199 + 31574861 = 31575060

Showing the first eight; more decompositions exist.
