Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453962, here are decompositions:

5 + 31453957 = 31453962
19 + 31453943 = 31453962
31 + 31453931 = 31453962
53 + 31453909 = 31453962
79 + 31453883 = 31453962
83 + 31453879 = 31453962
139 + 31453823 = 31453962
149 + 31453813 = 31453962

Showing the first eight; more decompositions exist.
