Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575364, here are decompositions:

3 + 31575361 = 31575364
11 + 31575353 = 31575364
53 + 31575311 = 31575364
83 + 31575281 = 31575364
131 + 31575233 = 31575364
257 + 31575107 = 31575364
383 + 31574981 = 31575364
503 + 31574861 = 31575364

Showing the first eight; more decompositions exist.
