Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562832, here are decompositions:

5 + 31562827 = 31562832
31 + 31562801 = 31562832
53 + 31562779 = 31562832
149 + 31562683 = 31562832
211 + 31562621 = 31562832
229 + 31562603 = 31562832
239 + 31562593 = 31562832
281 + 31562551 = 31562832

Showing the first eight; more decompositions exist.
