Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575334, here are decompositions:

23 + 31575311 = 31575334
53 + 31575281 = 31575334
101 + 31575233 = 31575334
113 + 31575221 = 31575334
173 + 31575161 = 31575334
227 + 31575107 = 31575334
293 + 31575041 = 31575334
353 + 31574981 = 31575334

Showing the first eight; more decompositions exist.
