Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186630, here are decompositions:

11 + 186619 = 186630
29 + 186601 = 186630
43 + 186587 = 186630
47 + 186583 = 186630
61 + 186569 = 186630
79 + 186551 = 186630
149 + 186481 = 186630
151 + 186479 = 186630

Showing the first eight; more decompositions exist.
