Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533652, here are decompositions:

11 + 31533641 = 31533652
41 + 31533611 = 31533652
53 + 31533599 = 31533652
71 + 31533581 = 31533652
89 + 31533563 = 31533652
191 + 31533461 = 31533652
239 + 31533413 = 31533652
263 + 31533389 = 31533652

Showing the first eight; more decompositions exist.
