Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26570, here are decompositions:

13 + 26557 = 26570
31 + 26539 = 26570
73 + 26497 = 26570
139 + 26431 = 26570
163 + 26407 = 26570
199 + 26371 = 26570
223 + 26347 = 26570
277 + 26293 = 26570

Showing the first eight; more decompositions exist.
