Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42880, here are decompositions:

17 + 42863 = 42880
41 + 42839 = 42880
59 + 42821 = 42880
83 + 42797 = 42880
107 + 42773 = 42880
113 + 42767 = 42880
137 + 42743 = 42880
179 + 42701 = 42880

Showing the first eight; more decompositions exist.
