Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126570, here are decompositions:

19 + 126551 = 126570
23 + 126547 = 126570
29 + 126541 = 126570
53 + 126517 = 126570
71 + 126499 = 126570
79 + 126491 = 126570
83 + 126487 = 126570
89 + 126481 = 126570

Showing the first eight; more decompositions exist.
