Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533014, here are decompositions:

13 + 31533001 = 31533014
43 + 31532971 = 31533014
151 + 31532863 = 31533014
181 + 31532833 = 31533014
277 + 31532737 = 31533014
421 + 31532593 = 31533014
433 + 31532581 = 31533014
463 + 31532551 = 31533014

Showing the first eight; more decompositions exist.
