Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563052, here are decompositions:

11 + 31563041 = 31563052
23 + 31563029 = 31563052
71 + 31562981 = 31563052
251 + 31562801 = 31563052
431 + 31562621 = 31563052
449 + 31562603 = 31563052
509 + 31562543 = 31563052
569 + 31562483 = 31563052

Showing the first eight; more decompositions exist.
