Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104380, here are decompositions:

11 + 104369 = 104380
53 + 104327 = 104380
71 + 104309 = 104380
83 + 104297 = 104380
137 + 104243 = 104380
149 + 104231 = 104380
173 + 104207 = 104380
197 + 104183 = 104380

Showing the first eight; more decompositions exist.
