Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454496, here are decompositions:

13 + 31454483 = 31454496
107 + 31454389 = 31454496
113 + 31454383 = 31454496
233 + 31454263 = 31454496
277 + 31454219 = 31454496
347 + 31454149 = 31454496
349 + 31454147 = 31454496
373 + 31454123 = 31454496

Showing the first eight; more decompositions exist.
