Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104668, here are decompositions:

17 + 104651 = 104668
29 + 104639 = 104668
71 + 104597 = 104668
89 + 104579 = 104668
107 + 104561 = 104668
131 + 104537 = 104668
197 + 104471 = 104668
251 + 104417 = 104668

Showing the first eight; more decompositions exist.
