Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508058, here are decompositions:

19 + 31508039 = 31508058
31 + 31508027 = 31508058
41 + 31508017 = 31508058
67 + 31507991 = 31508058
107 + 31507951 = 31508058
137 + 31507921 = 31508058
157 + 31507901 = 31508058
181 + 31507877 = 31508058

Showing the first eight; more decompositions exist.
