Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453948, here are decompositions:

5 + 31453943 = 31453948
17 + 31453931 = 31453948
107 + 31453841 = 31453948
269 + 31453679 = 31453948
419 + 31453529 = 31453948
521 + 31453427 = 31453948
557 + 31453391 = 31453948
587 + 31453361 = 31453948

Showing the first eight; more decompositions exist.
