Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533576, here are decompositions:

5 + 31533571 = 31533576
13 + 31533563 = 31533576
29 + 31533547 = 31533576
43 + 31533533 = 31533576
59 + 31533517 = 31533576
79 + 31533497 = 31533576
127 + 31533449 = 31533576
163 + 31533413 = 31533576

Showing the first eight; more decompositions exist.
