Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454724, here are decompositions:

23 + 31454701 = 31454724
43 + 31454681 = 31454724
71 + 31454653 = 31454724
73 + 31454651 = 31454724
97 + 31454627 = 31454724
137 + 31454587 = 31454724
211 + 31454513 = 31454724
227 + 31454497 = 31454724

Showing the first eight; more decompositions exist.
