Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563074, here are decompositions:

31 + 31563043 = 31563074
43 + 31563031 = 31563074
61 + 31563013 = 31563074
73 + 31563001 = 31563074
157 + 31562917 = 31563074
163 + 31562911 = 31563074
307 + 31562767 = 31563074
337 + 31562737 = 31563074

Showing the first eight; more decompositions exist.
