Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186662, here are decompositions:

13 + 186649 = 186662
43 + 186619 = 186662
61 + 186601 = 186662
79 + 186583 = 186662
181 + 186481 = 186662
193 + 186469 = 186662
211 + 186451 = 186662
271 + 186391 = 186662

Showing the first eight; more decompositions exist.
