Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5778, here are decompositions:

29 + 5749 = 5778
37 + 5741 = 5778
41 + 5737 = 5778
61 + 5717 = 5778
67 + 5711 = 5778
89 + 5689 = 5778
109 + 5669 = 5778
127 + 5651 = 5778

Showing the first eight; more decompositions exist.
