Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563174, here are decompositions:

11 + 31563163 = 31563174
37 + 31563137 = 31563174
43 + 31563131 = 31563174
47 + 31563127 = 31563174
101 + 31563073 = 31563174
131 + 31563043 = 31563174
173 + 31563001 = 31563174
191 + 31562983 = 31563174

Showing the first eight; more decompositions exist.
