Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575094, here are decompositions:

3 + 31575091 = 31575094
53 + 31575041 = 31575094
113 + 31574981 = 31575094
167 + 31574927 = 31575094
233 + 31574861 = 31575094
281 + 31574813 = 31575094
347 + 31574747 = 31575094
401 + 31574693 = 31575094

Showing the first eight; more decompositions exist.
