Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22562, here are decompositions:

13 + 22549 = 22562
19 + 22543 = 22562
31 + 22531 = 22562
61 + 22501 = 22562
79 + 22483 = 22562
109 + 22453 = 22562
181 + 22381 = 22562
193 + 22369 = 22562

Showing the first eight; more decompositions exist.
