Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575576, here are decompositions:

5 + 31575571 = 31575576
13 + 31575563 = 31575576
23 + 31575553 = 31575576
89 + 31575487 = 31575576
107 + 31575469 = 31575576
127 + 31575449 = 31575576
139 + 31575437 = 31575576
199 + 31575377 = 31575576

Showing the first eight; more decompositions exist.
