Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533188, here are decompositions:

61 + 31533127 = 31533188
97 + 31533091 = 31533188
229 + 31532959 = 31533188
307 + 31532881 = 31533188
439 + 31532749 = 31533188
601 + 31532587 = 31533188
607 + 31532581 = 31533188
691 + 31532497 = 31533188

Showing the first eight; more decompositions exist.
