Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518372, here are decompositions:

31 + 518341 = 518372
61 + 518311 = 518372
73 + 518299 = 518372
139 + 518233 = 518372
163 + 518209 = 518372
181 + 518191 = 518372
193 + 518179 = 518372
241 + 518131 = 518372

Showing the first eight; more decompositions exist.
