Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102678, here are decompositions:

5 + 102673 = 102678
11 + 102667 = 102678
31 + 102647 = 102678
67 + 102611 = 102678
71 + 102607 = 102678
127 + 102551 = 102678
131 + 102547 = 102678
139 + 102539 = 102678

Showing the first eight; more decompositions exist.
