Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68438, here are decompositions:

67 + 68371 = 68438
109 + 68329 = 68438
127 + 68311 = 68438
157 + 68281 = 68438
199 + 68239 = 68438
211 + 68227 = 68438
229 + 68209 = 68438
277 + 68161 = 68438

Showing the first eight; more decompositions exist.
