Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563182, here are decompositions:

19 + 31563163 = 31563182
109 + 31563073 = 31563182
139 + 31563043 = 31563182
151 + 31563031 = 31563182
181 + 31563001 = 31563182
199 + 31562983 = 31563182
223 + 31562959 = 31563182
271 + 31562911 = 31563182

Showing the first eight; more decompositions exist.
