Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533908, here are decompositions:

37 + 31533871 = 31533908
61 + 31533847 = 31533908
79 + 31533829 = 31533908
139 + 31533769 = 31533908
271 + 31533637 = 31533908
277 + 31533631 = 31533908
337 + 31533571 = 31533908
397 + 31533511 = 31533908

Showing the first eight; more decompositions exist.
