Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533938, here are decompositions:

19 + 31533919 = 31533938
67 + 31533871 = 31533938
109 + 31533829 = 31533938
277 + 31533661 = 31533938
307 + 31533631 = 31533938
367 + 31533571 = 31533938
421 + 31533517 = 31533938
439 + 31533499 = 31533938

Showing the first eight; more decompositions exist.
