Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27678, here are decompositions:

5 + 27673 = 27678
31 + 27647 = 27678
47 + 27631 = 27678
61 + 27617 = 27678
67 + 27611 = 27678
97 + 27581 = 27678
127 + 27551 = 27678
137 + 27541 = 27678

Showing the first eight; more decompositions exist.
