Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505934, here are decompositions:

7 + 31505927 = 31505934
11 + 31505923 = 31505934
13 + 31505921 = 31505934
113 + 31505821 = 31505934
127 + 31505807 = 31505934
151 + 31505783 = 31505934
167 + 31505767 = 31505934
193 + 31505741 = 31505934

Showing the first eight; more decompositions exist.
