Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486518, here are decompositions:

7 + 486511 = 486518
37 + 486481 = 486518
127 + 486391 = 486518
139 + 486379 = 486518
211 + 486307 = 486518
271 + 486247 = 486518
337 + 486181 = 486518
379 + 486139 = 486518

Showing the first eight; more decompositions exist.
