Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533098, here are decompositions:

7 + 31533091 = 31533098
97 + 31533001 = 31533098
127 + 31532971 = 31533098
139 + 31532959 = 31533098
199 + 31532899 = 31533098
349 + 31532749 = 31533098
439 + 31532659 = 31533098
547 + 31532551 = 31533098

Showing the first eight; more decompositions exist.
