Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575294, here are decompositions:

13 + 31575281 = 31575294
53 + 31575241 = 31575294
61 + 31575233 = 31575294
73 + 31575221 = 31575294
131 + 31575163 = 31575294
313 + 31574981 = 31575294
367 + 31574927 = 31575294
383 + 31574911 = 31575294

Showing the first eight; more decompositions exist.
