Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563056, here are decompositions:

13 + 31563043 = 31563056
43 + 31563013 = 31563056
73 + 31562983 = 31563056
97 + 31562959 = 31563056
139 + 31562917 = 31563056
229 + 31562827 = 31563056
277 + 31562779 = 31563056
373 + 31562683 = 31563056

Showing the first eight; more decompositions exist.
