Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454896, here are decompositions:

23 + 31454873 = 31454896
29 + 31454867 = 31454896
59 + 31454837 = 31454896
113 + 31454783 = 31454896
227 + 31454669 = 31454896
269 + 31454627 = 31454896
383 + 31454513 = 31454896
647 + 31454249 = 31454896

Showing the first eight; more decompositions exist.
