Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533962, here are decompositions:

3 + 31533959 = 31533962
13 + 31533949 = 31533962
43 + 31533919 = 31533962
139 + 31533823 = 31533962
193 + 31533769 = 31533962
199 + 31533763 = 31533962
241 + 31533721 = 31533962
331 + 31533631 = 31533962

Showing the first eight; more decompositions exist.
