Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508106, here are decompositions:

5 + 31508101 = 31508106
13 + 31508093 = 31508106
23 + 31508083 = 31508106
29 + 31508077 = 31508106
67 + 31508039 = 31508106
79 + 31508027 = 31508106
89 + 31508017 = 31508106
103 + 31508003 = 31508106

Showing the first eight; more decompositions exist.
