Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563058, here are decompositions:

17 + 31563041 = 31563058
29 + 31563029 = 31563058
71 + 31562987 = 31563058
257 + 31562801 = 31563058
281 + 31562777 = 31563058
347 + 31562711 = 31563058
431 + 31562627 = 31563058
491 + 31562567 = 31563058

Showing the first eight; more decompositions exist.
