Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572752, here are decompositions:

19 + 31572733 = 31572752
103 + 31572649 = 31572752
163 + 31572589 = 31572752
181 + 31572571 = 31572752
193 + 31572559 = 31572752
223 + 31572529 = 31572752
229 + 31572523 = 31572752
241 + 31572511 = 31572752

Showing the first eight; more decompositions exist.
