Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67818, here are decompositions:

11 + 67807 = 67818
17 + 67801 = 67818
29 + 67789 = 67818
41 + 67777 = 67818
59 + 67759 = 67818
61 + 67757 = 67818
67 + 67751 = 67818
109 + 67709 = 67818

Showing the first eight; more decompositions exist.
