Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563094, here are decompositions:

5 + 31563089 = 31563094
53 + 31563041 = 31563094
107 + 31562987 = 31563094
113 + 31562981 = 31563094
293 + 31562801 = 31563094
317 + 31562777 = 31563094
383 + 31562711 = 31563094
467 + 31562627 = 31563094

Showing the first eight; more decompositions exist.
