Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476884, here are decompositions:

3 + 31476881 = 31476884
13 + 31476871 = 31476884
31 + 31476853 = 31476884
37 + 31476847 = 31476884
151 + 31476733 = 31476884
157 + 31476727 = 31476884
181 + 31476703 = 31476884
193 + 31476691 = 31476884

Showing the first eight; more decompositions exist.
