Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563044, here are decompositions:

3 + 31563041 = 31563044
13 + 31563031 = 31563044
31 + 31563013 = 31563044
43 + 31563001 = 31563044
61 + 31562983 = 31563044
127 + 31562917 = 31563044
277 + 31562767 = 31563044
307 + 31562737 = 31563044

Showing the first eight; more decompositions exist.
