Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533556, here are decompositions:

23 + 31533533 = 31533556
59 + 31533497 = 31533556
107 + 31533449 = 31533556
167 + 31533389 = 31533556
347 + 31533209 = 31533556
389 + 31533167 = 31533556
557 + 31532999 = 31533556
617 + 31532939 = 31533556

Showing the first eight; more decompositions exist.
