Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454474, here are decompositions:

13 + 31454461 = 31454474
43 + 31454431 = 31454474
97 + 31454377 = 31454474
211 + 31454263 = 31454474
277 + 31454197 = 31454474
283 + 31454191 = 31454474
313 + 31454161 = 31454474
397 + 31454077 = 31454474

Showing the first eight; more decompositions exist.
