Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165570, here are decompositions:

11 + 165559 = 165570
17 + 165553 = 165570
19 + 165551 = 165570
29 + 165541 = 165570
37 + 165533 = 165570
43 + 165527 = 165570
47 + 165523 = 165570
59 + 165511 = 165570

Showing the first eight; more decompositions exist.
