Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454884, here are decompositions:

3 + 31454881 = 31454884
11 + 31454873 = 31454884
17 + 31454867 = 31454884
47 + 31454837 = 31454884
101 + 31454783 = 31454884
233 + 31454651 = 31454884
257 + 31454627 = 31454884
401 + 31454483 = 31454884

Showing the first eight; more decompositions exist.
