Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518450, here are decompositions:

3 + 518447 = 518450
19 + 518431 = 518450
61 + 518389 = 518450
109 + 518341 = 518450
139 + 518311 = 518450
151 + 518299 = 518450
211 + 518239 = 518450
241 + 518209 = 518450

Showing the first eight; more decompositions exist.
