Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575462, here are decompositions:

13 + 31575449 = 31575462
29 + 31575433 = 31575462
101 + 31575361 = 31575462
109 + 31575353 = 31575462
151 + 31575311 = 31575462
181 + 31575281 = 31575462
229 + 31575233 = 31575462
241 + 31575221 = 31575462

Showing the first eight; more decompositions exist.
