Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104428, here are decompositions:

11 + 104417 = 104428
29 + 104399 = 104428
47 + 104381 = 104428
59 + 104369 = 104428
101 + 104327 = 104428
131 + 104297 = 104428
197 + 104231 = 104428
281 + 104147 = 104428

Showing the first eight; more decompositions exist.
