Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533610, here are decompositions:

11 + 31533599 = 31533610
23 + 31533587 = 31533610
29 + 31533581 = 31533610
47 + 31533563 = 31533610
113 + 31533497 = 31533610
149 + 31533461 = 31533610
179 + 31533431 = 31533610
197 + 31533413 = 31533610

Showing the first eight; more decompositions exist.
