Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563292, here are decompositions:

23 + 31563269 = 31563292
71 + 31563221 = 31563292
83 + 31563209 = 31563292
251 + 31563041 = 31563292
263 + 31563029 = 31563292
311 + 31562981 = 31563292
443 + 31562849 = 31563292
491 + 31562801 = 31563292

Showing the first eight; more decompositions exist.
