Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508246, here are decompositions:

13 + 31508233 = 31508246
19 + 31508227 = 31508246
43 + 31508203 = 31508246
67 + 31508179 = 31508246
103 + 31508143 = 31508246
127 + 31508119 = 31508246
139 + 31508107 = 31508246
163 + 31508083 = 31508246

Showing the first eight; more decompositions exist.
