Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104988, here are decompositions:

17 + 104971 = 104988
29 + 104959 = 104988
41 + 104947 = 104988
71 + 104917 = 104988
97 + 104891 = 104988
109 + 104879 = 104988
137 + 104851 = 104988
139 + 104849 = 104988

Showing the first eight; more decompositions exist.
