Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165594, here are decompositions:

5 + 165589 = 165594
7 + 165587 = 165594
41 + 165553 = 165594
43 + 165551 = 165594
53 + 165541 = 165594
61 + 165533 = 165594
67 + 165527 = 165594
71 + 165523 = 165594

Showing the first eight; more decompositions exist.
