Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572052, here are decompositions:

3 + 31572049 = 31572052
11 + 31572041 = 31572052
23 + 31572029 = 31572052
59 + 31571993 = 31572052
89 + 31571963 = 31572052
173 + 31571879 = 31572052
353 + 31571699 = 31572052
401 + 31571651 = 31572052

Showing the first eight; more decompositions exist.
