Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454976, here are decompositions:

5 + 31454971 = 31454976
19 + 31454957 = 31454976
23 + 31454953 = 31454976
53 + 31454923 = 31454976
67 + 31454909 = 31454976
73 + 31454903 = 31454976
103 + 31454873 = 31454976
109 + 31454867 = 31454976

Showing the first eight; more decompositions exist.
