Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454674, here are decompositions:

5 + 31454669 = 31454674
23 + 31454651 = 31454674
47 + 31454627 = 31454674
191 + 31454483 = 31454674
233 + 31454441 = 31454674
353 + 31454321 = 31454674
557 + 31454117 = 31454674
593 + 31454081 = 31454674

Showing the first eight; more decompositions exist.
