Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454732, here are decompositions:

31 + 31454701 = 31454732
79 + 31454653 = 31454732
271 + 31454461 = 31454732
349 + 31454383 = 31454732
541 + 31454191 = 31454732
571 + 31454161 = 31454732
709 + 31454023 = 31454732
739 + 31453993 = 31454732

Showing the first eight; more decompositions exist.
