Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22642, here are decompositions:

3 + 22639 = 22642
5 + 22637 = 22642
23 + 22619 = 22642
29 + 22613 = 22642
71 + 22571 = 22642
101 + 22541 = 22642
131 + 22511 = 22642
173 + 22469 = 22642

Showing the first eight; more decompositions exist.
