Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68402, here are decompositions:

3 + 68399 = 68402
13 + 68389 = 68402
31 + 68371 = 68402
73 + 68329 = 68402
163 + 68239 = 68402
193 + 68209 = 68402
241 + 68161 = 68402
331 + 68071 = 68402

Showing the first eight; more decompositions exist.
