Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65668, here are decompositions:

11 + 65657 = 65668
17 + 65651 = 65668
59 + 65609 = 65668
89 + 65579 = 65668
131 + 65537 = 65668
149 + 65519 = 65668
311 + 65357 = 65668
359 + 65309 = 65668

Showing the first eight; more decompositions exist.
