Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104518, here are decompositions:

5 + 104513 = 104518
47 + 104471 = 104518
59 + 104459 = 104518
101 + 104417 = 104518
137 + 104381 = 104518
149 + 104369 = 104518
191 + 104327 = 104518
311 + 104207 = 104518

Showing the first eight; more decompositions exist.
