Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68500, here are decompositions:

11 + 68489 = 68500
17 + 68483 = 68500
23 + 68477 = 68500
53 + 68447 = 68500
101 + 68399 = 68500
149 + 68351 = 68500
239 + 68261 = 68500
281 + 68219 = 68500

Showing the first eight; more decompositions exist.
