Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575032, here are decompositions:

43 + 31574989 = 31575032
211 + 31574821 = 31575032
331 + 31574701 = 31575032
613 + 31574419 = 31575032
829 + 31574203 = 31575032
859 + 31574173 = 31575032
991 + 31574041 = 31575032
1033 + 31573999 = 31575032

Showing the first eight; more decompositions exist.
