Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533434, here are decompositions:

3 + 31533431 = 31533434
307 + 31533127 = 31533434
337 + 31533097 = 31533434
421 + 31533013 = 31533434
433 + 31533001 = 31533434
463 + 31532971 = 31533434
571 + 31532863 = 31533434
601 + 31532833 = 31533434

Showing the first eight; more decompositions exist.
