Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28842, here are decompositions:

5 + 28837 = 28842
29 + 28813 = 28842
53 + 28789 = 28842
71 + 28771 = 28842
83 + 28759 = 28842
89 + 28753 = 28842
113 + 28729 = 28842
131 + 28711 = 28842

Showing the first eight; more decompositions exist.
