Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563054, here are decompositions:

11 + 31563043 = 31563054
13 + 31563041 = 31563054
23 + 31563031 = 31563054
41 + 31563013 = 31563054
53 + 31563001 = 31563054
67 + 31562987 = 31563054
71 + 31562983 = 31563054
73 + 31562981 = 31563054

Showing the first eight; more decompositions exist.
