Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508324, here are decompositions:

13 + 31508311 = 31508324
37 + 31508287 = 31508324
97 + 31508227 = 31508324
181 + 31508143 = 31508324
223 + 31508101 = 31508324
241 + 31508083 = 31508324
307 + 31508017 = 31508324
373 + 31507951 = 31508324

Showing the first eight; more decompositions exist.
