Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 882, here are decompositions:

5 + 877 = 882
19 + 863 = 882
23 + 859 = 882
29 + 853 = 882
43 + 839 = 882
53 + 829 = 882
59 + 823 = 882
61 + 821 = 882

Showing the first eight; more decompositions exist.
