Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88880, here are decompositions:

7 + 88873 = 88880
13 + 88867 = 88880
19 + 88861 = 88880
37 + 88843 = 88880
61 + 88819 = 88880
67 + 88813 = 88880
73 + 88807 = 88880
79 + 88801 = 88880

Showing the first eight; more decompositions exist.
