Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476882, here are decompositions:

11 + 31476871 = 31476882
29 + 31476853 = 31476882
53 + 31476829 = 31476882
61 + 31476821 = 31476882
83 + 31476799 = 31476882
139 + 31476743 = 31476882
149 + 31476733 = 31476882
179 + 31476703 = 31476882

Showing the first eight; more decompositions exist.
