Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482694, here are decompositions:

11 + 31482683 = 31482694
53 + 31482641 = 31482694
107 + 31482587 = 31482694
293 + 31482401 = 31482694
401 + 31482293 = 31482694
521 + 31482173 = 31482694
647 + 31482047 = 31482694
653 + 31482041 = 31482694

Showing the first eight; more decompositions exist.
