Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16570, here are decompositions:

3 + 16567 = 16570
17 + 16553 = 16570
23 + 16547 = 16570
41 + 16529 = 16570
83 + 16487 = 16570
89 + 16481 = 16570
137 + 16433 = 16570
149 + 16421 = 16570

Showing the first eight; more decompositions exist.
