Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528962, here are decompositions:

53 + 31528909 = 31528962
109 + 31528853 = 31528962
131 + 31528831 = 31528962
139 + 31528823 = 31528962
149 + 31528813 = 31528962
151 + 31528811 = 31528962
211 + 31528751 = 31528962
233 + 31528729 = 31528962

Showing the first eight; more decompositions exist.
