Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68510, here are decompositions:

3 + 68507 = 68510
19 + 68491 = 68510
37 + 68473 = 68510
61 + 68449 = 68510
67 + 68443 = 68510
73 + 68437 = 68510
139 + 68371 = 68510
181 + 68329 = 68510

Showing the first eight; more decompositions exist.
