Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22688, here are decompositions:

19 + 22669 = 22688
37 + 22651 = 22688
67 + 22621 = 22688
139 + 22549 = 22688
157 + 22531 = 22688
241 + 22447 = 22688
307 + 22381 = 22688
397 + 22291 = 22688

Showing the first eight; more decompositions exist.
