Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575414, here are decompositions:

7 + 31575407 = 31575414
37 + 31575377 = 31575414
53 + 31575361 = 31575414
61 + 31575353 = 31575414
103 + 31575311 = 31575414
113 + 31575301 = 31575414
173 + 31575241 = 31575414
181 + 31575233 = 31575414

Showing the first eight; more decompositions exist.
