Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533004, here are decompositions:

3 + 31533001 = 31533004
5 + 31532999 = 31533004
23 + 31532981 = 31533004
131 + 31532873 = 31533004
137 + 31532867 = 31533004
227 + 31532777 = 31533004
311 + 31532693 = 31533004
317 + 31532687 = 31533004

Showing the first eight; more decompositions exist.
