Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22480, here are decompositions:

11 + 22469 = 22480
47 + 22433 = 22480
71 + 22409 = 22480
83 + 22397 = 22480
89 + 22391 = 22480
113 + 22367 = 22480
131 + 22349 = 22480
137 + 22343 = 22480

Showing the first eight; more decompositions exist.
