Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22988, here are decompositions:

67 + 22921 = 22988
127 + 22861 = 22988
181 + 22807 = 22988
211 + 22777 = 22988
271 + 22717 = 22988
337 + 22651 = 22988
349 + 22639 = 22988
367 + 22621 = 22988

Showing the first eight; more decompositions exist.
