Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104872, here are decompositions:

3 + 104869 = 104872
23 + 104849 = 104872
41 + 104831 = 104872
71 + 104801 = 104872
83 + 104789 = 104872
113 + 104759 = 104872
149 + 104723 = 104872
179 + 104693 = 104872

Showing the first eight; more decompositions exist.
