Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575262, here are decompositions:

29 + 31575233 = 31575262
41 + 31575221 = 31575262
101 + 31575161 = 31575262
263 + 31574999 = 31575262
281 + 31574981 = 31575262
293 + 31574969 = 31575262
401 + 31574861 = 31575262
449 + 31574813 = 31575262

Showing the first eight; more decompositions exist.
