Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68490, here are decompositions:

7 + 68483 = 68490
13 + 68477 = 68490
17 + 68473 = 68490
41 + 68449 = 68490
43 + 68447 = 68490
47 + 68443 = 68490
53 + 68437 = 68490
101 + 68389 = 68490

Showing the first eight; more decompositions exist.
