Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453936, here are decompositions:

5 + 31453931 = 31453936
53 + 31453883 = 31453936
113 + 31453823 = 31453936
257 + 31453679 = 31453936
359 + 31453577 = 31453936
509 + 31453427 = 31453936
653 + 31453283 = 31453936
743 + 31453193 = 31453936

Showing the first eight; more decompositions exist.
