Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5668, here are decompositions:

11 + 5657 = 5668
17 + 5651 = 5668
29 + 5639 = 5668
137 + 5531 = 5668
149 + 5519 = 5668
167 + 5501 = 5668
191 + 5477 = 5668
197 + 5471 = 5668

Showing the first eight; more decompositions exist.
