Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22406, here are decompositions:

37 + 22369 = 22406
103 + 22303 = 22406
127 + 22279 = 22406
277 + 22129 = 22406
283 + 22123 = 22406
313 + 22093 = 22406
367 + 22039 = 22406
379 + 22027 = 22406

Showing the first eight; more decompositions exist.
