Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165612, here are decompositions:

11 + 165601 = 165612
23 + 165589 = 165612
43 + 165569 = 165612
53 + 165559 = 165612
59 + 165553 = 165612
61 + 165551 = 165612
71 + 165541 = 165612
79 + 165533 = 165612

Showing the first eight; more decompositions exist.
