Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127668, here are decompositions:

5 + 127663 = 127668
11 + 127657 = 127668
19 + 127649 = 127668
31 + 127637 = 127668
59 + 127609 = 127668
61 + 127607 = 127668
67 + 127601 = 127668
71 + 127597 = 127668

Showing the first eight; more decompositions exist.
