Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68530, here are decompositions:

23 + 68507 = 68530
29 + 68501 = 68530
41 + 68489 = 68530
47 + 68483 = 68530
53 + 68477 = 68530
83 + 68447 = 68530
131 + 68399 = 68530
179 + 68351 = 68530

Showing the first eight; more decompositions exist.
