Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533002, here are decompositions:

3 + 31532999 = 31533002
31 + 31532971 = 31533002
43 + 31532959 = 31533002
79 + 31532923 = 31533002
103 + 31532899 = 31533002
139 + 31532863 = 31533002
349 + 31532653 = 31533002
409 + 31532593 = 31533002

Showing the first eight; more decompositions exist.
