Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83880, here are decompositions:

7 + 83873 = 83880
11 + 83869 = 83880
23 + 83857 = 83880
37 + 83843 = 83880
47 + 83833 = 83880
67 + 83813 = 83880
89 + 83791 = 83880
103 + 83777 = 83880

Showing the first eight; more decompositions exist.
