Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533266, here are decompositions:

7 + 31533259 = 31533266
139 + 31533127 = 31533266
307 + 31532959 = 31533266
367 + 31532899 = 31533266
433 + 31532833 = 31533266
607 + 31532659 = 31533266
613 + 31532653 = 31533266
673 + 31532593 = 31533266

Showing the first eight; more decompositions exist.
