Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67686, here are decompositions:

7 + 67679 = 67686
67 + 67619 = 67686
79 + 67607 = 67686
97 + 67589 = 67686
107 + 67579 = 67686
109 + 67577 = 67686
127 + 67559 = 67686
139 + 67547 = 67686

Showing the first eight; more decompositions exist.
