Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61668, here are decompositions:

11 + 61657 = 61668
17 + 61651 = 61668
31 + 61637 = 61668
37 + 61631 = 61668
41 + 61627 = 61668
59 + 61609 = 61668
107 + 61561 = 61668
109 + 61559 = 61668

Showing the first eight; more decompositions exist.
