Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533974, here are decompositions:

7 + 31533967 = 31533974
103 + 31533871 = 31533974
127 + 31533847 = 31533974
151 + 31533823 = 31533974
211 + 31533763 = 31533974
313 + 31533661 = 31533974
337 + 31533637 = 31533974
457 + 31533517 = 31533974

Showing the first eight; more decompositions exist.
