Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533688, here are decompositions:

29 + 31533659 = 31533688
47 + 31533641 = 31533688
89 + 31533599 = 31533688
101 + 31533587 = 31533688
107 + 31533581 = 31533688
191 + 31533497 = 31533688
227 + 31533461 = 31533688
239 + 31533449 = 31533688

Showing the first eight; more decompositions exist.
