Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68480, here are decompositions:

3 + 68477 = 68480
7 + 68473 = 68480
31 + 68449 = 68480
37 + 68443 = 68480
43 + 68437 = 68480
109 + 68371 = 68480
151 + 68329 = 68480
199 + 68281 = 68480

Showing the first eight; more decompositions exist.
