Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533604, here are decompositions:

5 + 31533599 = 31533604
17 + 31533587 = 31533604
23 + 31533581 = 31533604
41 + 31533563 = 31533604
71 + 31533533 = 31533604
107 + 31533497 = 31533604
173 + 31533431 = 31533604
191 + 31533413 = 31533604

Showing the first eight; more decompositions exist.
