Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5918, here are decompositions:

37 + 5881 = 5918
61 + 5857 = 5918
67 + 5851 = 5918
79 + 5839 = 5918
97 + 5821 = 5918
127 + 5791 = 5918
139 + 5779 = 5918
181 + 5737 = 5918

Showing the first eight; more decompositions exist.
