Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563232, here are decompositions:

11 + 31563221 = 31563232
23 + 31563209 = 31563232
83 + 31563149 = 31563232
101 + 31563131 = 31563232
191 + 31563041 = 31563232
251 + 31562981 = 31563232
383 + 31562849 = 31563232
431 + 31562801 = 31563232

Showing the first eight; more decompositions exist.
