Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42798, here are decompositions:

5 + 42793 = 42798
11 + 42787 = 42798
31 + 42767 = 42798
47 + 42751 = 42798
61 + 42737 = 42798
71 + 42727 = 42798
79 + 42719 = 42798
89 + 42709 = 42798

Showing the first eight; more decompositions exist.
