Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533094, here are decompositions:

3 + 31533091 = 31533094
113 + 31532981 = 31533094
227 + 31532867 = 31533094
317 + 31532777 = 31533094
401 + 31532693 = 31533094
521 + 31532573 = 31533094
587 + 31532507 = 31533094
617 + 31532477 = 31533094

Showing the first eight; more decompositions exist.
