Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453996, here are decompositions:

3 + 31453993 = 31453996
5 + 31453991 = 31453996
53 + 31453943 = 31453996
113 + 31453883 = 31453996
173 + 31453823 = 31453996
263 + 31453733 = 31453996
269 + 31453727 = 31453996
317 + 31453679 = 31453996

Showing the first eight; more decompositions exist.
