Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575064, here are decompositions:

5 + 31575059 = 31575064
23 + 31575041 = 31575064
83 + 31574981 = 31575064
137 + 31574927 = 31575064
173 + 31574891 = 31575064
251 + 31574813 = 31575064
317 + 31574747 = 31575064
383 + 31574681 = 31575064

Showing the first eight; more decompositions exist.
