Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533602, here are decompositions:

3 + 31533599 = 31533602
31 + 31533571 = 31533602
103 + 31533499 = 31533602
151 + 31533451 = 31533602
193 + 31533409 = 31533602
223 + 31533379 = 31533602
601 + 31533001 = 31533602
631 + 31532971 = 31533602

Showing the first eight; more decompositions exist.
