Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506024, here are decompositions:

31 + 31505993 = 31506024
41 + 31505983 = 31506024
97 + 31505927 = 31506024
101 + 31505923 = 31506024
103 + 31505921 = 31506024
181 + 31505843 = 31506024
211 + 31505813 = 31506024
223 + 31505801 = 31506024

Showing the first eight; more decompositions exist.
