Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22570, here are decompositions:

3 + 22567 = 22570
29 + 22541 = 22570
59 + 22511 = 22570
89 + 22481 = 22570
101 + 22469 = 22570
137 + 22433 = 22570
173 + 22397 = 22570
179 + 22391 = 22570

Showing the first eight; more decompositions exist.
