Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104920, here are decompositions:

3 + 104917 = 104920
29 + 104891 = 104920
41 + 104879 = 104920
71 + 104849 = 104920
89 + 104831 = 104920
131 + 104789 = 104920
191 + 104729 = 104920
197 + 104723 = 104920

Showing the first eight; more decompositions exist.
