Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508444, here are decompositions:

157 + 31508287 = 31508444
211 + 31508233 = 31508444
241 + 31508203 = 31508444
337 + 31508107 = 31508444
367 + 31508077 = 31508444
463 + 31507981 = 31508444
523 + 31507921 = 31508444
547 + 31507897 = 31508444

Showing the first eight; more decompositions exist.
