Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68390, here are decompositions:

19 + 68371 = 68390
61 + 68329 = 68390
79 + 68311 = 68390
109 + 68281 = 68390
151 + 68239 = 68390
163 + 68227 = 68390
181 + 68209 = 68390
229 + 68161 = 68390

Showing the first eight; more decompositions exist.
