Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454396, here are decompositions:

7 + 31454389 = 31454396
13 + 31454383 = 31454396
19 + 31454377 = 31454396
199 + 31454197 = 31454396
313 + 31454083 = 31454396
373 + 31454023 = 31454396
439 + 31453957 = 31454396
487 + 31453909 = 31454396

Showing the first eight; more decompositions exist.
