Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185664, here are decompositions:

13 + 185651 = 185664
23 + 185641 = 185664
43 + 185621 = 185664
71 + 185593 = 185664
97 + 185567 = 185664
107 + 185557 = 185664
113 + 185551 = 185664
131 + 185533 = 185664

Showing the first eight; more decompositions exist.
