Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22470, here are decompositions:

17 + 22453 = 22470
23 + 22447 = 22470
29 + 22441 = 22470
37 + 22433 = 22470
61 + 22409 = 22470
73 + 22397 = 22470
79 + 22391 = 22470
89 + 22381 = 22470

Showing the first eight; more decompositions exist.
