Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186678, here are decompositions:

7 + 186671 = 186678
29 + 186649 = 186678
31 + 186647 = 186678
59 + 186619 = 186678
97 + 186581 = 186678
109 + 186569 = 186678
127 + 186551 = 186678
197 + 186481 = 186678

Showing the first eight; more decompositions exist.
