Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482882, here are decompositions:

23 + 31482859 = 31482882
43 + 31482839 = 31482882
59 + 31482823 = 31482882
61 + 31482821 = 31482882
83 + 31482799 = 31482882
103 + 31482779 = 31482882
139 + 31482743 = 31482882
173 + 31482709 = 31482882

Showing the first eight; more decompositions exist.
