Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68220, here are decompositions:

7 + 68213 = 68220
11 + 68209 = 68220
13 + 68207 = 68220
59 + 68161 = 68220
73 + 68147 = 68220
79 + 68141 = 68220
107 + 68113 = 68220
109 + 68111 = 68220

Showing the first eight; more decompositions exist.
