Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563006, here are decompositions:

5 + 31563001 = 31563006
19 + 31562987 = 31563006
23 + 31562983 = 31563006
47 + 31562959 = 31563006
89 + 31562917 = 31563006
157 + 31562849 = 31563006
179 + 31562827 = 31563006
227 + 31562779 = 31563006

Showing the first eight; more decompositions exist.
