Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518330, here are decompositions:

3 + 518327 = 518330
19 + 518311 = 518330
31 + 518299 = 518330
97 + 518233 = 518330
139 + 518191 = 518330
151 + 518179 = 518330
193 + 518137 = 518330
199 + 518131 = 518330

Showing the first eight; more decompositions exist.
