Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188736, here are decompositions:

7 + 188729 = 188736
17 + 188719 = 188736
29 + 188707 = 188736
43 + 188693 = 188736
59 + 188677 = 188736
83 + 188653 = 188736
103 + 188633 = 188736
127 + 188609 = 188736

Showing the first eight; more decompositions exist.
