Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575214, here are decompositions:

53 + 31575161 = 31575214
107 + 31575107 = 31575214
173 + 31575041 = 31575214
233 + 31574981 = 31575214
353 + 31574861 = 31575214
401 + 31574813 = 31575214
467 + 31574747 = 31575214
491 + 31574723 = 31575214

Showing the first eight; more decompositions exist.
