Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68538, here are decompositions:

7 + 68531 = 68538
17 + 68521 = 68538
31 + 68507 = 68538
37 + 68501 = 68538
47 + 68491 = 68538
61 + 68477 = 68538
89 + 68449 = 68538
101 + 68437 = 68538

Showing the first eight; more decompositions exist.
