Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454634, here are decompositions:

7 + 31454627 = 31454634
47 + 31454587 = 31454634
137 + 31454497 = 31454634
151 + 31454483 = 31454634
173 + 31454461 = 31454634
193 + 31454441 = 31454634
251 + 31454383 = 31454634
257 + 31454377 = 31454634

Showing the first eight; more decompositions exist.
