Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104842, here are decompositions:

11 + 104831 = 104842
41 + 104801 = 104842
53 + 104789 = 104842
83 + 104759 = 104842
113 + 104729 = 104842
131 + 104711 = 104842
149 + 104693 = 104842
191 + 104651 = 104842

Showing the first eight; more decompositions exist.
