Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572952, here are decompositions:

3 + 31572949 = 31572952
11 + 31572941 = 31572952
71 + 31572881 = 31572952
83 + 31572869 = 31572952
239 + 31572713 = 31572952
311 + 31572641 = 31572952
401 + 31572551 = 31572952
419 + 31572533 = 31572952

Showing the first eight; more decompositions exist.
