Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454694, here are decompositions:

13 + 31454681 = 31454694
41 + 31454653 = 31454694
43 + 31454651 = 31454694
67 + 31454627 = 31454694
107 + 31454587 = 31454694
181 + 31454513 = 31454694
197 + 31454497 = 31454694
211 + 31454483 = 31454694

Showing the first eight; more decompositions exist.
