Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454664, here are decompositions:

11 + 31454653 = 31454664
13 + 31454651 = 31454664
37 + 31454627 = 31454664
151 + 31454513 = 31454664
167 + 31454497 = 31454664
181 + 31454483 = 31454664
223 + 31454441 = 31454664
233 + 31454431 = 31454664

Showing the first eight; more decompositions exist.
