Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186744, here are decompositions:

11 + 186733 = 186744
17 + 186727 = 186744
37 + 186707 = 186744
43 + 186701 = 186744
73 + 186671 = 186744
97 + 186647 = 186744
157 + 186587 = 186744
163 + 186581 = 186744

Showing the first eight; more decompositions exist.
