Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571336, here are decompositions:

3 + 31571333 = 31571336
79 + 31571257 = 31571336
193 + 31571143 = 31571336
337 + 31570999 = 31571336
397 + 31570939 = 31571336
463 + 31570873 = 31571336
733 + 31570603 = 31571336
829 + 31570507 = 31571336

Showing the first eight; more decompositions exist.
