Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454454, here are decompositions:

13 + 31454441 = 31454454
23 + 31454431 = 31454454
71 + 31454383 = 31454454
103 + 31454351 = 31454454
191 + 31454263 = 31454454
233 + 31454221 = 31454454
257 + 31454197 = 31454454
263 + 31454191 = 31454454

Showing the first eight; more decompositions exist.
