Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185766, here are decompositions:

13 + 185753 = 185766
17 + 185749 = 185766
19 + 185747 = 185766
29 + 185737 = 185766
43 + 185723 = 185766
59 + 185707 = 185766
67 + 185699 = 185766
73 + 185693 = 185766

Showing the first eight; more decompositions exist.
