Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104838, here are decompositions:

7 + 104831 = 104838
11 + 104827 = 104838
37 + 104801 = 104838
59 + 104779 = 104838
79 + 104759 = 104838
109 + 104729 = 104838
127 + 104711 = 104838
131 + 104707 = 104838

Showing the first eight; more decompositions exist.
