Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104440, here are decompositions:

23 + 104417 = 104440
41 + 104399 = 104440
47 + 104393 = 104440
59 + 104381 = 104440
71 + 104369 = 104440
113 + 104327 = 104440
131 + 104309 = 104440
197 + 104243 = 104440

Showing the first eight; more decompositions exist.
