Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533694, here are decompositions:

53 + 31533641 = 31533694
83 + 31533611 = 31533694
107 + 31533587 = 31533694
113 + 31533581 = 31533694
131 + 31533563 = 31533694
197 + 31533497 = 31533694
233 + 31533461 = 31533694
263 + 31533431 = 31533694

Showing the first eight; more decompositions exist.
